I only have nightmares. That's all I ever have, meds or not. I had to come up with a different definition of nightmares for myself, since all my dreams are what other people call nightmares. I only really call it a "nightmare" when I wake up and realize it was a dream and I'm still scared anyway. That's pretty rare.
Funny, I have nightmares about tornadoes too, although I've never seen one.
Choose the devil you don't know.
