Does it really? It doesn't feel that real when you know it's a dream. All the dreams I can remember are always ones that I know it's a dream.
"rare phenomenon and lucid dreams can seldom be summoned at will, which has made it difficult for researchers to capture them in the lab in a reliable manner."
I mean, I can't summon them at will, but I do tend to dream most nights, and they're (as far as I can remember) always lucid.
I'm looking forward to more info about dreams and lucid dreams. I wonder if there's any correlation to stuff like dementia or early death. It seems like lucid dreaming is very tiring and that I don't wake well rested (I should add that I can generally control or struggle to control what goes on in the dream, so that might be part of it).
