sleepy from violent dream

I went to sleep 'late', maybe around 1am, but I woke up at 6:30 because of a horrible dream.

I usually don't have dreams like this one. It was really violent, the beating women kind of violent. In fact I've only had that kind of dream three times. I wonder about my brain when I have dreams like this, was it a specific event that triggered it or was it just too much tv or is there some evil piece in my mind that feeds on things like this or does some demon know where to jab his spear in my brain to trigger these thoughts no matter what I'm doing... It had made me really tired though. Even though I slept I got no rest and woke up early. I guess part of me didn't want to watch the television of my brain. I spent the next hour and half sleeping and waking in a chair... I heard Helen leave on her scooter, and I finally got up and showered and rode into work.
