I worry that people can read my thoughts
For as long as I can remember I've thought that people were reading my thoughts. Whenever I heard someone laughing behind me I was sure that they were mocking my silly ideas. Even if there's no one near by, I still feel that I need to protect mind. I've never considered wearing a tinfoil hat, there's no way it'd help.
What's particularly aggravating is that I'm sure that they aren't very good at reading my mind, so I'll explain what I'm doing/thinking out loud to make sure there are no misunderstandings.
I know it's irrational, but I still freak out when I think people are invading my own thoughts.
