Last summer I went on a church youth trip to the Cleveland, OH area (i'm a theist, which means I believe in a higher power but not a certain religion, but was forced to go regardless) while we were there I had a "sleep-walking" incident. Third night in, I got out of my bed in my sleep, ran and jumped up onto the bars of my friend's bunked, then lifted the rest of myself up and rolled onto the bed with him in it. The shaking began to wake him up. I started to tear at the lock on the window above his bed. He began to whisper to me to try to figure out what was going on, and as soon as he made a sound I turned around and stared him in the eyes.
The strange thing is this is where I realized what I was doing but couldn't control my body as if my eyes where only windows through someone else's body. I could feel or in a way see what it was feeling, this beast inside me. It was craving to kill him and destroy every matter of his being and I could feel it's power and I knew it could. A surge of pain rain through my head and I regained control. With my friend now whispering louder in fear repeating over and over "what are you doing? What are you doing?!", I chocked on my response and decided to jump off the bed. As soon as I hit the ground I lost control again. I don't remember moving over to the door that exits the room but I do remember opening it. I didn't open it with my hand I remember me just walking towards the door as it opened for me but I could feel it open the door with its mind. I don't know what happened after and that which I do know we pieced together from 3 of the guys who woke up to it (the friend who spoke played it off as a strange night terror after enough time), I don't know where I went and it scares me.
After that I began to piece older memories together, such as accidentally breaking a girls collar bone at summer camp (I tripped in a hole and tried to catch myself on her and even though I didn't touch her she began to scream in agony) and I started to realize that the two were correlated in some form of survival instinct (judging from the fact that the other form of my mind seemed like an animal in nature). There have been multiple sleepwalking incidents where I come downstairs and tear food out the fridge and pantry and eat it (especially lunch meats and cereal) creating large messes like a raccoon came into our house. But an incident that happened after scared me the most. I was in the library room of our house playing my guitar when I dropped into a seizure like-state. The whole time a image burned in my head of myself and another version of my self standing across from each other but a dark blurry figure stood off-center but in-between us. I remember the figure having some form of animal skull on top its head and wearing a robe with a staff or some form of long rod in his hands but most was hard to make out since he seemed to be almost composed of smoke.
I would enjoy opinions on what this could be. I don't think it's possession since the other person feels like me but I don't understand what the vision could mean. Regardless, Thanks for reading this.
