Hi! I've been reading about all these neat practical things you can do while lucid, like practice the piano and such. But what about studying for an exam? Is it possible to read a book in waking life and then request it in a dream or is the mind incapable of storing that kind of massive structured information? If possible, could you then read it in your dream?
I haven’t had a LD yet, and I hardly ever remember my dreams (working on that one) but I’ve read that texts often change if you look away for a second.

Sorry for the nerdy question. I know that dreams are for fun, but it would be awesome to learn while sleeping.
