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?
Sound, definitely at times. More commonly when outside sounds (traffic, construction, etc) get incorporated into my dream. I feel like sometimes I experience knowledge of sound in my dreams (responding to things that would require hearing it in IRL, like speaking) but don’t actually remember hearing anything, because dream logic.
Smell is more rare in my dreams, and I don’t think I’ve ever experienced any very lovely smells in my dreams. But I have smelled a horrible rotting smell in my dreams before.
