Why do you think I dream about the devil so much?

I have allot dreams about the devil.I had one last night that I was in my room it started to rain.I noticed footprints in the rain.I ran to my mothers room to tell her.Then a man came in walk through the door.He was wearing a black suit. He rainto me jump inside of me like a ghost. them my mother told me once the devil was in me. Their was no getting rid of him.It was scary I get really bad dreams. Their are times I wake up screaming.
