This has been a question that's been bugging me for a loooong time, though I've had no one to ask it to. How associative are dreams to memories? I mean this by a few things. For one, from a dream, particularly lucid, are you capable of recalling any memory? If so, with how much clarity? I've seen snow once in my life, when I was maybe 7 or 8. I was wondering if after I'm capable of altering my own lucid dreams, if I could recall how snow looks and feels just like how it was then, or would it be just what my mind thinks it would feel like?

(I'm fascinated =P)
