I’ve been having this problem for about the past year or so. it's like I'm sharing my body with someone else, but not my mind. (sounds bizarre, i know.) I don’t know what’s been causing it, it just sort of happens. It typically lasts from a few hours to a few days, but once it happened for a few weeks. When this happens, I cannot recognise the objects/places/people around me. I know that I know these places/things/people, but it does not feel like my things or friends etc. I will also completely forget the realationship i have to people and can only view them as people, not siblings/parents/boyfriend etc. I become very angry at everything and everyone, and have violent and intrusive thoughts about hurting or even killing other people. This leads me to staying in my room and not talking to people for hours. an example of this was when it happened at school last term, I had english and went for a walk mid class. I walked around and became increasingly more angry for no reason. I kept thinking about hurting the people i walked past and decided i was going to buy a lighter the next day and set the school on fire. when I arrived back to class, without thinking about it, when the substitute teacher left the room and everyone was focused I got up and grabbed the spray bottle of bleach that was behind me and imediately sprayed it into the socket on the wall and turned it on. I will look in the mirror but I do not recognise that person as me. Not at all. I become VERY paranoid about the people around me, and usually will not eat food given to me ‘just incase’ and often feel like everyone is out to get me/hurt me and that no one can be trusted. Though I also feel incapable of feeling scared and that no matter what I do, I am incapable of being harmed and that I am above everyone else, which is contradictory but it’s just what happens. The world around me looks different, but not just like how I said earlier. The color and feel is different, and can either be brighter and more colorful than usual or the opposite. When it's happening I desperately want to dye/cut my hair, get new clothes, or get piercings to try to change the way I look as fast as I can but obviously don't act on it. when it's happening, cannot see consequences for things and can only listen to the same artists' music while it's happening. When this happens, and I'm back to being me, I can't remember the majority of the time that it has happened. I can’t recall things I did, people I talked to, or what I've eaten or anything like that. If I can recall something from it, it feels very very distant and far away in my mind and like it was a dream. I will be convinced that the people around me are not real and I am the only real person, everyone else is just made up and fake. When it’s happening, time goes almost in slow motion and sometimes when people speak, I can only hear them speak in slow motion. When it’s happening I will also often think I am seeing spiders crawling on me, on the walls, or over things on the floor out of the corner of my eye, though then realize it isn’t real after inspection. Eating food when it's happening is strange not only because I'm so paranoid, but because the texture and taste is different.
