Scary dream I had. (not too nsfw)

This happened a while ago. In the dream, I was in my house only it was very dark, like a black fog. It was also night. I couldn't see very far into any of the rooms. I looked down my corridor and on the other side of the glass of the front door, there was a black figure staring back at me. My mother then explained to me that my father had people over the other night and he was dead. A rotten meat smell filled the house and I could hear flies. I managed to get a torch and I shone it on my mother. She stared back at me and then I moved the torch light over to her left, and there is another exact copy of my mother. I know one is evil. They both look at each other and then one chased the other up the stars, and I ran after. I could hear screaming and howling as I run up the stars with the torch flailing about. I ran up and found my dad lying dead on my parent's bed, in a pool of blood. That's when I woke up, surprisingly not that frightened.
