Violent Dreams

Last night, for the third night in a row, I had a dream where I was giving someone a right good beating. Seriously - hair-pulling, kicking, punching in the face. The first night it was a 20-something man in a 1980's style red jogging suit who stole my wallet, the second night it was an old lady who had broken in and was defiantly squatting in the his enormous house in which I was baby-sitting/house-sitting, and last night it was this big, fat, mobster looking guy, who was a hospital administrator who had refused to admit my pregnant and car-accident-injured friend, and she ended up losing her baby. Needless to say, in every instance I was protecting somebody, or at least trying to make two wrongs equal a right (is that better than randomly beating on people?). The dreams have been incredibly vivid and detailed and long (I've only put in a teeny bit of detail here), but in each one, I have wound up either sitting on the victims chest and punching them in the face or grabbing them by the hair, and banging their head against the ground.

I'm extremely disturbed by these dreams. I mean, I know they're just dreams, and better I beat someone up in my dreams than in real life, but it makes me wonder if it's something I would be capable of? Is there a part of me that is THAT violent? That angry? I know I've been pretty stressed out and all, but this seems excessive.
