I have noticed it before, but I guess because I am trying to more aware of what I am feeling and why, I have noticed I become semi-paranoid or just paranoid. On my walk today, I had the feeling for the longest time that I was being followed, but there of course was no one behind me.

For years, I would get that feeling, but usually only when I was driving, when car was behind me. Especially if it happened to be making the same turns. I'd get real up tight, and the feeling would persist long after the car continued on, after I made a turn.

It's a little un-nerving.
