Dreams

So lately I've been having some pretty wacked out dreams and nightmares. People that I know have been in them and then people who I have no clue who they are are in them. It's really insane. I hate having such vivid dreams because they make my back hurt the whole next day.
Another thing is that they make me toss and turn and roll over and roll back. I wake up in all sorts of weird positions that even I didn't know I could get into.
I don't know why I've been having such weird dreams, but I just wish they would stop. I'd like to have ONE good night of sleep before Christmas.
I had one thought, while at lunch the other day with my friend Cody, that maybe it's from all the scary, disgusting, gory movies I've been watching. I don't think so because I've watched worse movies and been completley fine. So, basically, I have no idea whats causing this. I haven't done anything to feel guilty about. I haven't killed someone. I haven't insulted someone beyond repair. I haven't eaten anything bad. I'm not sick. I have NO IDEA!
What does one do to stop such horrid, recurring events every night.
