Things people are scared of

I got out of bed last night in cold sweat coz I thought I had a bunch of crickets in my bed. At that point I was wondering(yes I was still covered in sweat) what people are really afraid of. I am afraid of the following: Ghosts,Insects,Geeks and people tell me that I'm terrified of the INS(I have no clue why). So what are YOU scared of?
