going crazy in my sleep

I have had memorable nightmares, or at least really twisted dreams, everynight for almost 2 weeks straight. Last night I had another instance of sleep paralysis, moments when my eyes are wide open (or I think they are at least) but I can't move or speak. This time it wasn't quite so scary because I didn't really attempt to move or anything. But it was extra weird because I suddenly decided I was someone else. Before bed I had read the bio of the author of a book I'm reading (Woman Warrior). In the middle of the night it felt like I opened my eyes and thought to myself, I'm now Maxine Hong Kingston (the author). Then laid there for awhile and then went back to sleep. I think I'm definitely losing my mind.
