What does it mean to have a dream about YOU being a demon?

Last night I had a dream that I became a demon... Full out red eyes, canine teeth. I just radiated evil. Throughout this dream I was seeing different people that I know, and others that I have seen on TV. Most of these people are people that I like, but for some reason my mother was there as well. She wasn't actually my mother though; physically, she looked like someone else. I remember her trying to get me to get out of the state, and saying that I was doing wrong. There was a dog there too, a small one... I don't really understand why my mother was there, because we don't exactly have the best relationship. It was as if, she was saying that she wanted me to stop the rampage, but she was encouraging it. After all of that, I ended up in a restaurant with all of my family. A few of my family members were drunk, and angry. It's really out of character for them. And once again, my mother was there, but she was trying to go after my little half sister. She's not related to her at all and never sees her, but for some reason... My mom was bent on getting her to sit next to her. This all seems very strange to me... Help?
