I'm always afraid when I'm in a public place that I'm being talked about and I haven't noticed yet, and that people are ridiculing me. For example, if I walk past a group of people and they start laughing, my first reaction is shame because I think they are laughing at me. Sometimes I think that people can hear me think or that I say all my thoughts out loud, and others don't tell me. I'll even think loudly to a person next to me to tell me they can hear my thoughts. It's annoying, and I keep thinking I must be schizotypal when I feel that way.
My parents used to try to see what I was doing on the computer (nothing wrong, but I really value my privacy), so I have a lingering fear that my computer's being monitored or that there is a camera watching me. They never actually monitored my computer or installed a camera (I think) so I don't know why I have that problem.
I tend to alternate between being too trusting of people and mistrusting them. It's usually nothing more than cynicism though.
