Though time is commonly refered to as the 4th dimension, its one way nature sets it apart from geometric space which we free to move about and back at will. I believe this is because it is made out of energy, motion. Therefore change is primary and our endeavor to order it results in time. Subjectively we could consider taste, smell or color to be extra dimensions. Quantumly? perhaps spin, charm, truth &beauty could be considered extra dimensions.
