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?
No smell in dreams for myself but yes sounds, although if being honest most the times the sounds are from voices ( not always).
Visuals are always there, and I don’t say sight because I sometimes see my dreams in 3rd person.
I’ve experienced touch but it’s selective, often more some kind of proprioception while I fall, fly, swim etc.
I’ve tasted things in dreams though, very few times but it’s there.
