I figured /x/ was the place to go for this. Had a series of nightmares last night where a jet black hammerhead shark looking demon attempted to possess me. I remember realizing that I was in a dream and trying to wake up, but the demon kept trying to keep me asleep. I ended up having a bizarre wrestling match with him for my mind, he bit my ankle, but wasn't physically in his presence in the dream. His image would briefly flash into my mind and we would continue fighting.
Thought it was kind of noteworthy that the dreams took place in places I recognized (my apartment and my office) and that everything was accurate. By that I mean that when I dream of places I've been, those places have bizarre changes to the layout of a room that don't resonate until I wake up, in these dreams everything was remarkably accurate. Except for the mind-wrestling match.
Anyways, it felt a lot like sleep paralysis, which I've experienced minor bouts of before. Had anyone else experienced something similar? If I see that smug motherfucker again tonight I'm going to try to kill him.
