> Can you remember what something smells like? I can recall a foul smell, but I don’t recoil because it doesn’t actually feel like smelling. Still, I have an impression of the smell. Sight works the same for me.

Can't get a foul smell reaction mentally, but if I visualize eating a bag of salt & vinegar potato chips and recall the taste I'll get extra saliva production. Not with most other foods so I think it's more mouth preparing to dilute the acid than just straight pavlov saliva before feeding reaction.
