Those Flashing Lights.

Whenever I drive at night I am most on edge about getting pulled over. I'm constantly on the look out for light bars on the top of cars. Thinking about this as I drove home from dropping off my girlfriend tonight I began to wonder what do other people fear at night? Lets face it peoples fright goes up exponentially when it gets darker out mostly because it's harder to see things. Is the guy walking behind you going to fallow you home, is he going to mug you? What about the creepy crawlies that you don't see during the day? Will the raccoon give you rabies or is that rat going to bite you?

If I do in fact have any readers what makes you afraid at night?
