I get this sometimes when i'm hypomanic. The worst and most embarrassing time was when i confronted my neighbor about it. She was really sweet and assured me i was imagining things. I later apologized for over-reacting and she was very kind about it. One time i confronted someone i caught talking about me with a guy and she explained the guy was saying how much he admired how assertive i was and she was telling him to ask me how i got that way! Well, i sure felt like a horse's *** that time!
