Arachnophobia. I once jumped out of a moving vehicle when a medium sized spider jumped onto my leg. The sad part? I was the driver! I did slam on the brakes, but I didn't slip the car into park once I jumped out. Thankfully my wife reacted quickly enough and managed to jump into the drivers seat and put the car into park.

Beyond that, I dislike being around large groups of people. Anything more then 5-10 people and I start getting extremely antsy and would rather leave then stay.

I'm scared of heights when I feel like I'm not in a safe place. Planes and roller coasters are fine. Standing on the edge of a tall building, not so much. I really want to go sky diving. I'm interested in how I would react.

My weird fear is my fear of flossing. It's a disgusting fear, I know, and a seemingly outrageous one. Maybe not so much a fear as a horribly extreme dislike for it. I hate the feeling of the floss between my teeth and I have this fear that the floss will go down into the roots of my tooth and cut them and rip the tooth out. I'm cringing just thinking and typing about it. Ugh.
