My Spawn had one of those really neat dreams recently, that I'm going to steal for a magical working soon.
In his dream, he was playing video games (yes, he's a young male through and through). As is so often the case, the character he was playing had the option of buying some tools/skills. One of the options was to buy 60 dreams. He bought that.
Apparently, since that time, he's been remember his dreams FAR more than ever before in his life.
I'm wondering what he paid for this ability, mind you. Still, this concept is one I can work with!
