wow, those are some intense dreams. I have had dreams similar to those, not a nightly occurrence. I love scary movies, some gore, mostly hauntings, exorcisms, real stories. I do not know what it is, I like the adrenaline rush it gives me, freaking myself out. I do know if I watch things like that throughout the week, give it a few days and I will most definitely dream something like that. You could just have a very active imagination. I'm not sure what those kinds of dreams do to the mental state of a person, but I wouldn't worry too much. I know when I have bizarre dreams I ask myself and others "What in the world is wrong with my brain?". But I do think it's just my wild imagination, and love for scary things.
