Sensation comes from the actual physical signals sent out by observed events and received by various organs of the body light transmitted from a view to an observer's eye or the sound waves travelling from a person's yell to a hearer's inner ear, for example. In both of these cases, the actual sensation occurs when the light/sound waves contact the observer/hearer's eye/ear. Perception, on the other hand, is what the observer or hearer actually perceives after this physical event has taken place; it involves many other mechanisms of the body and the brain and thus can be much different from person to person. That is, the same sensory event (sight, sound, etc) might cause a very similar sensation for two equally-abled observers but lead to very different perceptions of that event based on how their body and mind process the sensation. Because no two people are going to have identical bodies or identical minds, it is highly unlikely that any two people will develop precisely the same set of perceptions from the same set of sensations. Imagine two different witnesses to a car accident, for example. One is somewhat hard of hearing and was almost hit by one of the cars immediately prior to the accident, while another person further down the street was
