Hmm in terms of paranoia I also think that laughter is always about me. Any time someone around me laughs or talks to someone else I know it's about me and become hostile and freak out. I can't seem to see that no one is even paying attention to me most likely. Also since I was a child I thought that when my parents are drunk (which was and still is very often) that they will get so drunk and angry they will accidentally murder me in my sleep. :/ I see people looking and judging me and I'm not always positive that's actually happening. I may be just seeing things.
Dissociation can happen without warning. Usually my boyfriend snaps me out of it. Apparently my eyes glaze over and I breathe different staring into space. Stress can make it happen. Sometimes I say things and thirty seconds later I don't even remember speaking.
