Clearly my eyes aren’t* open and I cannot take in external visual stimuli in my dreams, however I experience them similar to the visual experience in my minds eye or imagination or whathaveyou. Similarly I feel like I experience something akin to touch or feel (like the occasional flying or falling dream, or the feel of grass or something).

I don’t recall having anything similar to smell or sound in a dream though (except occasionally hearing a real sound while waking up that wasn’t actually part of the dream) What’s your experience?
