Dream of hands

I was with my best friend and we were watching a film. In the film, there was a young boy who was looking for someone and somehow he ended up in an autopsy room, he laid down on the bed/table thing and started chopping sausages (literally) and somehow the boy threw the sausages at my friend and I. After cutting the sausages, the boy looked at his hands and started cutting his hands, there was blood everywhere, a police officer came and saw what happened, he looked at the boy and vomitted all over the boys hands and then he fainted. The boy then proceeded on cutting his body open. I looked to my friend and said "i'm going to the toilet" I went to the sink and started vomitting blood and chunks of skin. Needless to say, I couldnt sleep after that. It was horrifying and gross!
