I think something is very wrong with me.

I've always been a more spiritual person. Seeing things from the side of my vision, people and hearing loud voices that don't exist. Yesterday it got worse. I was in bed ready to fall asleep when I heard someone yelling my name. It sounded like my late father, it sounded very much angry which startled me and got me up. I had my windows and curtains closed, but something told me I shouldn't open them. I did anyway. The moment I opened my curtains I saw something in the form of a demon. But with my father's face grinning at me. I got so scared because I knew I was not dreaming. I didint know what to do. Because it kept grinning at me and speaking in a weird language I didint know of. Through the moment of panic I slammed my head in the wall across from the window of my room, it took only a few hard times for me to fall unconscious.
