nightmare catcher?

I dreamt that I had to watch a friend - I don't know who - while she was being raped.
That's what I woke up from this morning. Shitty way to start the day. That and news about the air strikes against the Taliban. I need a new alarm clock. I want one of those Zen alarm clocks that chime instead of ringing or beeping or playing the news.

I have a dream catcher over the bed. I cover the mirror at the foot of the bed at night with a veil. I'm at a loss about how to stop these nightmares. Horrible dreams like that one have been haunting me for at least a year. Maybe I'll try chi gong before I go to bed. Maybe I need to try some magic.

What the hell is my subconscious doing to me?
