I'm glad you posted this question, because I often wonder the same. I also have what seems to me rather excessive fears about being unsafe...attacked, murdered, whatever. For example, even when I'm taking the short walk to get my mail I lock my apartment door for fear someone will come in and let my cats out and hide in the closet. Even though the door has been securely locked, after I retrieve my mail and unlock the door I sometimes go to the closet just to be sure no one is in there.

I often have the 'feeling' that someone is watching me with bad intentions. I always feel vulnerable when I get into my car, and I lock the doors immediately, as soon as I possibly can.

If I saw a hole in the wall, a tiny hole, I don't think I would feel suspicious, but I can definitely understand why you feel that way.

Anyway, I've often wondered whether I'm paranoid, or whether I am simply reacting to the weird world at a time when crime seems rampant.

So. I wish I had a better answer for you! I don't have an answer, but it seems that either we're both paranoid or we both are reacting to a potentially unsafe world.
