Think you might have been watching too many Alfred Hitchcock movies. I remember after watching some of those horror movies, I would always feel that someone was watching me. Of course it wasn't true.

Don't you wonder where those people get their ideas for writing those movies.....maybe you could take come of your paranoia & put a plot to it.......you could become a millionair movie writter......then your paranoia could be put to good use.

I am not trying to make light of it honestly......I just remember feeling those paranoid feelings after watching movies like that....only way I could relate to what you are going through.
