We can easily recall our visual stimulus and auditory stimulus but why can't we recall chemical stimulus like smell and pain?

We can recall a song or picture but we can't exactly recall smell and pain. Why is that so?

    $\begingroup$ This appears, at least to me, a very subjective question that would have to be discussed philosophically rather than with empirical evidence. An interesting topic nonetheless! $\endgroup$ – James Jul 10 '15 at 1:07

    $\begingroup$ Olfactory memories are among the most powerful known. They are so strong that copious salivation occurs when people are directed to think of biting into a lemon or a sourball. What is the basis for your question? $\endgroup$ – anongoodnurse Jul 10 '15 at 3:36
