Is it normal that i constantly dream of being gang raped, and like it?

I have almost nightly dreams about being raped. I wake exilerated. The dreams are always different people, usually people I have seen that day or have seen on TV. The dreams are very graphic. I am always raped by multiple people (both sexes), sometimes I look up and can't see the end of the sea of people waiting their turn. I feel pain in the dreams, although it is always masked with at least a little pleasure. At the point that the rape would normally kill me i wake. I absoulutly love the dreams. I even find myself daydreaming of ways to make it all real.
