Extremely creepy

Last night I had a dream that my arm was like rubber and going every which way while holding a gun and it started shooting on its own. I was in a panic that I would hit someone and I kept trying to use my other hand to control it and point it at the ground but I couldn't. This morning my roomate told me that she had a dream that she had been shot in the neck and it felt so real that it actually woke her up from her sleep.
