OK, so this has been bothering me for a few years, and I never thought to ask here. So there is a book series I read when I was in grade school, which means it could have ranged from anything from a YA novel to a regular Fiction series because I read them all.
Things I remember:
*The main character could go into a different place when he slept
*There were many worlds in this place
*He could bring things back when traveling there in dreams, which you aren't supposed to be able to do
*Other people can get there, but you have to like go around a long way
*His uncle comes and takes him away to teach him to be a wizard
*There is a girl in an Egyptian type world where they aren't allowed to have books
*He takes her books and she hides them in the "space" above her shoulder
*There was something about a wizards or sorcerers signature that was unforgable or something along those lines.
*One of the spells I remember a silencing spell and he once cast it so strongly when trying to talk to his mom without his uncle hearing that they had to "dig" through the spell to make a way for them to talk to each other.
So yeah, does this sound familiar to anyone? I would appreciate anything, it's one of those books you read a LONG time ago and really liked but you can't remember what it is. I would just really really like to read it again.
