I've always had vivid, often memorable dreams. Sometimes, when I try to recall a memory of a place, I'll pull up something about a dream that took place there and have to remind myself that it was my brain, not my true experience, that conjured that aspect of the place.
I don't mean plots of dreams stick with me (sometimes they do, but not often. Usually when I write down a plot of a dream it makes sense for a while but when I read it as soon as a few weeks later I'll think WTF? Huh? ) it's more sensations or bits of them that stick as strongly as true memory. I can recall the feel of flying almost as clearly as I can remember what it's like to stand with my feet sinking into sand when the edge of waves wash over them.
Anyway, I wonder if this is part of the brain of a fiction writer? I'd look this up, but I'm lazy. Not enough sleep. Too many dreams.
