I dunno if this is a ghost story, but sometimes when I have violent/disturbing nightmares, I'll hear shit in the room and in the outside in the distance, like weird banging, clanging noises. My nightmares are always frightening and gory. Then I'll wake up by the noises I hear and be conscious but completely unable to move and I'll see this kind of wispy stuff above me. And I have to will myself very hard to make it go away and get control of my body again..

I think it might just be the way my body reacts to nightmares, like half waking up and my consciousness is still in the dream but my body is also somewhat awake but still unable to move. I don't really believe in an afterlife, but maybe there is shit out there on another plane that can interact with ours. There's so much out there we don't understand I feel its possible.
