Ok, I'll say this now because im dying to mention it, and if i say it at the end of this post it'll derive from topic. I just saw the film "The Cell" and thought to myself, albeit quite gory and not really what most would nessicerilly 'want' to dream about (heres hoping ), This is a HELL'of alot like Lucid Dreaming.... to some extent.

Anyway,

I was wondering if its possible at all to recall memories in your LD's.
I've read of peoples experiences in dreams of the big ball in the sky thats supposedly your mind/ego, and obviously we should take into account that our subconcious should really be all-knowing of our own knowledge, as far as im aware anyway. (Note that I have only had one Lucid and I didn't interact with any DC's or Talk to myself or whathaveyou in anyway.)

With sufficient Dream Recall Skill, could you awaken from a dream being slightly wiser, having replayed certain events in your life making you more aware of outcomings? Could you re-live maths lessons and rekindle lost equations?

If anybody has experienced this sort of dream or knows an honest answer they could share then please, by all means, share your thoughts.
