My experience of dreams is full immersion in the plot, visuals, audios. It feels real... Unless I get a few moments of lucidity(knowing I'm dreaming) but the experience has full visuals even if I'm lucid. I can't pull up an image at will while I'm awake though.
For me also, I think I never really knew that others were actually seeing something, when asked to visualize and other senses. It seems psychotic to see and hear and smell and taste things that are not presently happening, but as a way of remembering or imagining?. I can remember great details of memories though and I do get hypnogogic imagery before sleep. I ran into the idea of aphantasia on a reddit with other people doing metaphysical exploration, where one guy said he was an aphant and so, couldn't visualize. I'm still not totally convinced this isn't some matter of semantics. Like I watched a comedienne on TV last night and I remember the dress she had on, but I don't see it when I close my eyes, as I would see some random hypnogogia, falling asleep.. Maybe, if I do have this, I've compensated by remembering as much detail as possible in life. The differences in memory ability and attention to detail, also seem relevent, maybe actually obscuring the subject for me.. I do have the fuzzy childhood thing, but I'm 65yo. and attributed that to my crappy childhood. LOL. I'm left handed, very good at spacial perception and other leftie skills.
