Dreams Actually Virtual Reality Threat Simulation?

Time Slows Down writes "Psychology Today has an interesting story on a new theory of why we dream. Finnish psychologist Antti Revonsuo believes that dreams are a sort of nighttime theater in which our brains screen realistic scenarios simulating emergency situations and providing an arena for safe training. 'The primary function of negative dreams is rehearsal for similar real events, so that threat recognition and avoidance happens faster and more automatically in comparable real situations,' he says. We have 300 to 1,000 threat dreams per year — one to four per night and just under half are aggressive encounters: physical aggression such as fistfights, and nonphysical aggression such as verbal arguments. Faced with actual life-or-death situations — traffic accidents, terrorist attacks, street assaults — people report entering a mode of calm, rapid response, reacting automatically, almost without thinking. Afterward, they often say the episode felt unreal, as if it were all a dream. 'Dreaming is a sensitive system that tries to pay much attention to the threatening cues in our environment,' Revonsuo says. 'Their function is to protect and prepare us.'"

Well, I'm not really a dream interpretation expert, but I play one on the Net. Anyway, many dreams are just the mind's way of working out problems -- or calling attention to problems -- that are currently occurring in our lives. Most of what occurs in people's dreams is more of a metaphor for something else.

      Take, for example, the oft-cited 'I dreamt that I showed up to work/school/whatever naked/wearing only underwear.' Showing up to work naked isn't actually the real problem the brain is trying work out. The real problem is that the person is a afraid of being unprepared or being caught in an embarassing situation. They are usually insecure about something or other when they have dreams like this. This is the brain trying say "Hey, you! You're insecure about this or that, what are you doing to fix that?"

      Of course, the imagery of dreams isn't always that universal. In your case, what do Einstein and Hawking represent for you? What about zebras? What does playing poker mean to you? Do you bluff a lot in poker? Or do you play on the merits of your cards? If you're a physicist, and just making guesses here about the zebra, I'd say that you that see Einstein and Hawking as a black-and-white dichotomy that needs to somehow be resolved. Maybe you think one of Hawking's theories and another of Einstein's are in deep conflict and maybe you see yourself as trying to resolve that. Of course, if you're not a physicist, the dream could mean something else entirely.

REM sleep is REM sleep; there are no different "categories" of REM sleep. And clearly, most of our dreams have nothing whatsoever to do with preparing us for threats.

But some people are born congenitally deaf. These "false" results don't render my idea incorrect- and my suspicion is that this is because "purpose" means something different in an evolutionary context than it does when we speak of other intelligent agents that have purposes.

      So what sense does it make to say that a behavior or phenomenon produced by evolution has a "purpose"? I think "the purpose of X is Y" is verbal shorthand for saying "Y is an effect of X, which accrues some net reproductive benefit". In that interpretation, a single "false" result is not sufficient. Some dreams don't do their "job". But as long as enough of them do, and you live incrementally longer and have more long-lived children as a result, then the dreams will have fulfilled their evolutionary "purpose".

Given that you aren't conscious of every mental process, it's not hard to imagine that your mind can train itself without conscious knowledge. I think it's roughly analogous to code that runs faster without debugging turned on: If you could be conscious of even *some* of your background mental processes, they'd be slowed down--and you'd be spending lots of your awake time just to watch, let alone interpret the debugging output.

      Our brains work without our consciousness--and given training, they do far better without our consciousness. Consider the pianist playing Flight of the Bumblebee flawlessly, who suddenly becomes conscious of his/her fingers. For a more common activity, who among us can do that cool pencil-spinning trick, and who can't--or remembers trying to learn it?. Mistakes are far more likely with the conscious mind engaged.

      And even, if you do remember a dream, they fade away in minutes after you wake up.

      A "bad sleep" is characterized by not entering REM sleep, because of waking up too often. REM sleep needs up tp 4 hours typically to manifest (but can earlier, e.g. 1 1/2 hours). thats why 4-5 hours of sleep is recommended.

      Daydreamer is a computer model of the stream of thought I developed at UCLA from 1983 to 1988. It implements the following:

      * daydreaming goals: strategies for what to think about
      * emotional control of thought: triggering and direction of processing by emotions
      * hierarchical planning: achieving a goal by breaking it down into subgoals
      * analogical planning (chunking): storing successful plans and adapting them to future problems

      * serendipity detection and application: a mechanism for recognizing and exploiting accidental relationships among problems

Since anyone can have a theory, I propose that dreams are merely the replay of the day's events or the 'echo firing' of thoughts you have had that day. My (admittedly small) reading suggests that the conscious portions f the brain actually act more as a filter and control of a vast number of underlying random neural events rather than a generator.

    It would make sense then that the conscious portions of the brain, needing to sleep at some point, shuts down the body with 'sleep paralysis' (this is state in which your motor functions are intentionally impaired and you cannot move your extremities even if you try - sometimes you can become conscious in this state briefly) and basically lets the unconscious portions of the brain have at it, which starts with the cohesive patterns the conscious brain had recently established and then, as the randomness takes hold without a controller, eventually corrupts into odd dreams. When the conscious brain starts taking control again at different times in the sleep cycles or upon awakening, this is connected to memory again and some of it bleeds over into conscious memory while the conscious portions of the brain are still establishing control.

      Interesting that a lot of these dreams seem to be focused on some kind of conflagration or strife. Here are a few snapshots of various dreams I've had over the years that I consider to be peaks into alternate realities along with the time frame in which I had the dreams:

      1. 1992: A world where everyone was in a simulation that was created to protect our minds from the reality that our planet was literally decaying into chunks and there was nothing that could be done to save everyone. So those left behind were thrown into simulation machines that made us think that everything was normal and business as usual as the planet broke up over years. I happened to be in a simulation array that was near a fault line and was jarred awake and started prowling around the abandoned city. There was more than just me too... I found my wife, but she didn't recognize me outside of the simulation and we were caught by guards who were supposed to take us to the next available set of simulation bays. I knew that I would have my memories wiped of my life with my family. I wasn't going to let it happen and tried to take things into my own hands...

      2. 1999-ish: My wife and I came back from a night out but I was still feeling a bit peckish. I told her I was going out for a snack and would be in a little later. She smiled and said OK as she went into our house. I then dropped forward onto my belly and face and slithered into the grassy field behind the parking area. I caught a rabbit and ate it whole. I then stood up, retracted my fangs and wiped the blood off of my face. I was a little annoyed that I'd chipped a tooth during the outing.

      3. 1989: I was in my old bedroom in my parent's house but it looked wrong. There was more furniture in it than I normally have (I'm a minimalist) and the time period looked like a strange cross between World War II era and the 80s. There was a personal computer in my room but it had a steel case that enveloped the monitor and computer and was built as part of the desk. Think of the old 40s/50s teacher's desks to get a mental image. The ones with the rounded corners everywhere. The computer was the same design. There was also a photo of me and my girlfriend (no one I really knew). I was in uniform and it seemed like it was war time. I wasn't really in the room but was more observing the room. I could tell that I was apparently dead and had been killed in the war. I then went out into the city and saw lots of mixes of 40s and 80s style cars, clothes and street scenes.

      4. 1970s (these dreams were a serial that lasted from 1974-1988). They started with me being a young child around three or four and being in a hiding spot to hide from soldiers of some kind (very Nazi looking). My parents (different from my real parents) had been killed and I was scared. Hiding in the closet. A young woman with black hair and black leather clothing ran into the closet, grabbed me and took off out of the back of the house with me. She then hopped onto a motor cycle and rode through the country side. Each time I rejoined her in the dreams we were either running away from someone, or trying to plant bombs to fight the oppressors, or she was teaching me math and language (not english and very unrecognizable characters). As I got older I grew attracted to her and the feeling became mutual (I won't "go there"). Eventually she died while we were trying to escape from our latest resistance fighting. I wasn't able to go back for her and she always told me to never sacrifice myself for anyone but the greater good which was to defeat our oppressors. I remember in the last dream that there was a wall around a city that we were trying to destroy. There was some kind of sign on one part of it in blue neon lighting. Again, it was in that strange language.

      5. Early 90s: The most interesting (in my opinion) was one where I had just left a university setting that seemed like a mixture of Victorian styles with some modern electrical devices here and there (like telephones). I walked

    Interesting concept, but wouldn't modern dreams have adapted to modern problems by now? I also thought (perhaps incorrectly) that the flight or fight response was mostly subconscious. So would "dream training" even help you in those situations?

    I would personally think dreams are more hormonal than that. A while back I began taking a vitamin supplement of zinc and magnesium (ZMA). A side effect of this vitamin combo is vivid dreaming. You notice right away that your dreams are more lucid, and you remember more of them. Right away I noticed that my dreams were very violent or sexually oriented. Now this vitamin supplement increases testosterone production as well (when combined with exercise). So I'm not quite sure if my violent/sexual dreams increased as a result of testosterone production, or that I was already having these dreams, and my memory/frequency of them was improved. I happen to think it is the latter because you notice the dreams on the first night of taking the vitamins.

    Either way, my dreams include fights, wars, sexual encounters, robberies, and all sorts of crazy behavior that just simply doesn't apply to my life. If dreams were a virtual reality training program, I wonder why they haven't adapted to train me for my real world problems that need solving. Not robbing a bank Heat style (a rather lucid dream I had the other night).

    I suppose the socially embarrassing dreams such as arriving to work naked might be a counter-point, but I just don't buy it.

    On that related note if anyone is interested in lucid dreaming, I highly recommend it. Google around for some quick guides. It's not very hard and requires very small amounts of simple self-hypnosis to start. Simply thinking of the question during your waking hours over and over again "Am I awake or am I dreaming" was enough for me to start asking myself that question while I was dreaming after a week. Once this question appears in your dreams and you recognize it enough to answer "dreaming", you can have lots of fun with lucid dreaming.

    I highly recommend the vitamin ZMA (Zinc Magnesium Aspartame) combined with valerian root* 30 minutes before bed. Also keep a dream log for maximum enjoyment. Lucid dreaming can be a lot of fun. Trying to get to know your own subconscious is a real challenge and it never gets boring.

    *Valerian root has very very pungent odor that can make your breath smell for hours after you take it. It sits in your stomach and seems to work its way up, no matter how clean your mouth is. It also has the reverse effect of pineapple juice, if you catch my drift. Thankfully ZMA on it's own is enough to enhance your dreams.

Since the poor mouse was prevented from doing the reformat on /dev/swap, it didn't work so well the next day, and the mouse's short-term sensory memory of what was in its environment was degraded. You might as well have given it a few hard knocks on the head.

    (3) REM sleep is just a weird, accidental by-product of some necessary biochemical house-cleaning that goes on at night. Some metabolic side-product chemical gets produced, and it jiggles the imagination handle randomly in the brain while we're asleep. The resulting images don't mean a damn thing, any more than the flashes in the eye when you rub your tired eyes. But because the mouse was prevented from doing the biochemical house-cleaning, whatever it is, he didn't function as well the next day.

Humans are supposed to be vital creatures of enormous power which cannot so easily be controlled or enslaved. --And this is why every effort today seems to be made by our keepers to make us dull and sleepy and forgetful of what we really are; eternal creatures, fragments of the infinite.

      Now perhaps I was mistaken, and perhaps the intent of the researchers in question was not this, but I could see in the poster's response, (whose comment I was answering), that tendency to put pat answers on the shelf rising once again as a broad possibility for many if such a theory ever became popular. And what a shame that would be! To believe our dream selves are merely a defense mechanism when they are so much more. All it takes is for one's beliefs to embrace such a limited view for it to gradually become a personal reality. How sad and totally unnecessary that would be! One more step into sleep.

      Reductionist science? What is that?

      Reductionist science is all the best science as we know it. --Science attempts to break down observed patterns into digestible chunks; to reduce them, as it were, preferably into segments which can be mathematically described, and thereby better understand them.

      What does state approval have to do with anything?

      State approval was my (obviously inadequate) way of summing up the nature of our governments and education systems today. --That is, ideas which are not sanctioned by news casters on television become things which are not considered by the populace to be real. i.e., subjects which we can legitimately think about in our private moments without feeling silly or shameful. This is the internal policeman at work, installed by the state, governing our thoughts, (if we allow it.) UFO's and Crop Circles are examples of such thoughts. The only way for many people to accept that anything is now officially real is if the official organs of 'truth' dissemination declare them so, (or by a similar degree, by neglecting to specifically say that such and such an idea is NOT officially real). --Science and 'expert testimony' are the defacto benchmarks of so-called 'truth' in the media these days, and if science were to declare that dreams are so-and-so and such-and-such, and if this official truth were carried through our schools and popular programming, (the Discovery Channel), and on and on, then that would simply be the end of that for many people. --Especially slashdotters, who I tend to view as both the gatekeepers of reality, since they pay attention to learning and knowledge, and because of this are also subject to the heaviest control measures with regard to what they are allowed to think.

Just under half are aggressive encounters: physical aggression such as fistfights, and nonphysical aggression such as verbal arguments. The rest are about car crashes, falling and drowning, missing a meeting or a test, being lost or trapped, and being naked in public.

The form and content of dreams is not random but organized and selective: during dreaming, the brain constructs a complex model of the world in which certain types of elements, when compared to waking life, are underrepresented whereas others are overrepresented. Furthermore, dream content is consistently and powerfully modulated by certain types of waking experiences. On the basis of this evidence, I put forward the hypothesis that the biological function of dreaming is to simulate threatening events, and to rehearse threat perception and threat avoidance. To evaluate this hypothesis, we need to consider the original evolutionary context of dreaming and the possible traces it has left in the dream content of the present human population. In the ancestral environment human life was short and full of threats. Any behavioral advantage in dealing with highly dangerous events would have increased the probability of reproductive success. A dream production mechanism that tends to select threatening waking events and simulate them over and over again in various combinations would have been valuable for the development and maintenance of threat avoidance skills. Empirical evidence from normative dream content, children's dreams, recurrent dreams, nightmares, post-traumatic dreams and the dreams of hunter-gatherers indicates that our dream production mechanisms are in fact specialized in the simulation of threatening events, and thus provides support to the threat simulation hypothesis of the function of dreaming.

      The threat simulation theory of dreaming is expressed in the form of six propositions, each of which is empirically testable. The propositions can be summarized as follows:

      1. Dream consciousness is an organized and selective simulation of the perceptual world.

      2. Dream consciousness is specialized in the simulation of threatening events

      3. Nothing but exposure to real threatening events fully activates the threat simulation system.

      4. The threat simulations produced by the fully activated system are perceptually and behaviorally realistic rehearsals of threatening events.

      5. The realistic rehearsal of these skills can lead to enhanced performance regardless of whether or not the training episodes are explicitly remembered.

      6. The ancestral environment in which the human brain evolved included frequent dangerous events that constituted extreme threats to human reproductive success. They thus presented serious selection pressures to ancestral human populations and fully activated the threat simulation mechanisms.

    This kind of ties into the earlier thread on mind doping using various prescription drugs to enhance thinking and reasoning. In particular, I've found beta-blockers, like Atenolol, tend to directly affect the brain even when asleep to some pretty useful levels. My own experiences were able to unlock certain aspects, such as lucid dreaming as well as controlled simulation of real-world problems with fairly usable results.

    Unlike the type of thinking we typically do when awake, this actually allows you to take some more abstract and unconventional liberties you wouldn't ordinarily think of under normal circumstances. It's surprisingly useful for evaluating and countering logical uncertainties in things like computer programming. Of course, the medication did occasionally cause some extremely vivid dreams that would have given Salvador Dali a run for his money, but it was pretty rare after a while.

    As for regular dreaming as threat simulation, it could be suggested that such medications directly alter how your mind prioritizes information, causing benign situations to be treated as traumatic, thus committed to memory more clearly, rather than being compressed and archived randomly. However, it's hard to say at this point if there is a net negative effect related to repeated exposure of such scenarios. For example, is it possible to take on so much "relevent" data, that it starts to hinder or even prevent any further "relevent" data from being stored for future use? (Sort of like how some vietnam vets suffer from "shell shock", and eventually become overly paranoid of their home surroundings.)

  110. Possible Purpose Of Sleeping by MystHunter · · Score: 1

    I think I may have "discovered" a possible evolutionary purpose of sleeping. The first is that dreaming helps your brain reinforce old pathways to memories that may have been lost or close to lost. Well what is the brain doing while asleep? It seems that the brain randomly activates bunches of neurons without letting large chain reactions of firing neurons get out of control. The brain spends almost all of it's energy gathering, interpreting, and then storing data. So, the stored data is the most important element for long term survival. The human brain is large and complex, memories are forgotten. In order to refresh important data and or safeguard data from deletion, data that may not have been accessed actively during waking consciousness is instead activated during sleep. The more often a memory is accessed, the more connections are made towards it and the harder it is for that memory to be lost. It's very simple but seems the most logical explanation, but would also explain why people have dreams containing things that they haven't thought about in 20+ years. The other possible reason for dreaming would be that of comparison. There is the waking state, where realities laws and properties are in effect, and then their is the sleeping state, where almost anything is possible. By letting the animal compare these two worlds, more can be understood about the waking world. When looking at something as complex as reality, it would be easier to understand it if another reality was presented to compare and contrast to it. Just possibilities, and maybe these are just one of many functions of sleep; in fact they probably are. Any thoughts?

    I had a great nightmare a few weeks ago. I was traveling somewhere with my wife, sitting at a pleasant outdoor cafe. My hands were developing hives or pimples or some sort of skin condition. So I said, "there's a pharmacy, let me go get some cream or lotion for this crap." It was one of those big chain pharmacies- I think it was a CVS. (Not the version control system, which has also appeared in nightmares.) My wife said she'd wait at the cafe, and I never saw her again. But during the rest of the dream, I "knew" she was waiting there.

    The pharmacy morphed into a hospital as I approached. A doctor was lounging in the doorway. He was a composite of two real life characters: an internist who had given me an unpleasant procedure when I was in college, and a jewelry store owner in Cupertino where I had a watch fixed a few days before (he sits in front of his store like that, waiting for business). I showed him my hands and he led me upstairs, told me to strip, and wheeled me down a corridor in a wheelchair. Meanwhile this stuff had been spreading up my arms and appearing on any skin elsewhere that had been in contact. So I was trying to avoid touching anything.

    We headed into a dingy wing of the hospital (think Jacob's Ladder ). As the wheelchair creaked down the hallway, more and more lights were flickering or burnt out. Rainwater was dripping from the ceiling and accumulating in puddles underneath. People were abandoned, crying from their beds, strapped to gurneys and convulsing, and the ceiling was starting to drip blood in places. We reached a room with a few empty cots, and he told me to wait there. Then he was gone.

    So I was sitting and waiting on this cot, trying to avoid touching anything, but the inflammation was continuing to spread- on my feet, ankles, up my knees, and all around my waist. My face itched like hell and the skin on my hands and arms was completely burnt and peeling off. Sometimes faceless nurses wearing masks would walk by, and I'd call out, trying to get their attention (I still needed that lotion I was hoping to get at the pharmacy). Usually they ignored me. I got the attention of a few, but when they saw the disease they ran away in terror.

    In came a crowd of second graders on a school trip. Two teachers were telling the kids to behave, and I quickly covered up my privates with my diseased filthy hands. (This had predictable dermatological results, but if I hadn't done it, MSNBC's Chris Hansen might have shown up. MSNBC pollutes my subconsciousness with that garbage whenever I don't pay attention after Olbermann's show is over.) I motioned to one of the teachers and whispered, "Pssst, do you really think it's a good idea to bring a bunch of little kids to a place like this on a school trip?"

    "Oh don't worry- they have their permission slips signed," she says, "and besides, you look great... except for your skin condition." (She was right- I've been getting exercise recently.) Meanwhile the kids had formed a semicircle around me and were pointing and giggling, calling me a monster.

    What about the dreams where you aren't able to do normal tasks? Like the dream where you are driving a Ferrari (or other fast sports car), but no matter how hard you press the gas, you still go slow. Or the dream where you're in a fight and you feel like you can only in slow motion (while the other person is in normal speed)? This seems to be a fairly common type of dream from talking to friends.

    Are these just one type of the potential problems that your brain is training you for? In order to come up with different scenarios about one subject, the brain could rely on some standard types of challenges. These challenges could make sense for some situations, but not for others. This could explain why some dreams are nonsense.

  147. it's all just mumbo jumbo by snapdragonflie · · Score: 1
    Biological studies have shown that when an animal follows a maze many times during the day, neurons in the hippocampus fire in a certain pattern. That night while the animal sleeps, the neurons fire in the same pattern. Are they "rehearsing" the maze?

    There have been other studies linking dreaming to memory. When people are deprived of REM sleep, their memory works less well. This is probably at least partly due to being tired or less alert, but there is a component that is stronger for things they were exposed to on the previous day. One of the primary theories in dream research (from a neurobiological viewpoint at least) is that dreams work to solidify memories. During the day, information (about events that happen to you or just things you hear) is stored in one area of the brain (probably the hippocampus, short-term memory, which is different from working memory which is more of a phenomenon of reverberation in the prefrontal cortex). While you sleep, the brain replays the information so that it can be more permanently stored in long-term memory (probably the entorhinal cortex). We know at least some of this through studies of people with damage to the hippocampus or the entorhinal cortex, along with the sleep studies mentioned above and lots of animal studies.

    The dreams themselves are probably just your brain trying to make sense of a series of random information that is being replayed. The actual important thing is likely to be the stream of imformation, which is probably not as coherent as even the most wild dreams. My dreams tend to jump all over the place, people turning into other people, myself teleporting to all sorts of random places.

    We also know that memories can be altered any time they are replayed. This does suggest that a dream could help you practice for a given scenario, since when you're in the scenario itself you would probably act the way you remember from the dream. However, it's unlikely that this was the actual purpose of the dream.

  148. wishful thinking by Jeremy_Bee · · Score: 1

    I thought this sounded more like wishful thinking than research ... then I had that thought confirmed by going to the site.

    The very to of the page tells us:

    - It's an article by "Psychology Today" of all things, (and we all know what great serious scientific credentials they have.)
    - The author is not a psychologist and not a doctor of any kind.

    Reading the actual article we find the research is highly questionable as to what they are measuring and to how the experience might translate from a rat to a human subject.

    Doing a little reading up on the background we find that:

    - the theory has been put forward before (not new)
    - the consensus *already* exists that this is *one* of the functions of dreams (not exclusive explanation)
    - the theory cannot explain the structure of all dreams (not conclusive)
    - other theories abound, each with about as much experimental support as this one (not unique)

    The only rational conclusion is that it's an interesting idea that has been thought of before but never proven. This latest experiment changes pretty much nothing about that, and not only doesn't rule out other theories, it fits rather well with the suggestion that dreams have many multiple uses/causes.

    In short, there is absolutely nothing new at all here.
