I have a few fears. Some are normal and rational. For instance, I'm afraid that my car might break down at any moment. This is a good fear because it helps me to be prepared for that situation.
    Other fears are somewhat irrational. I'm afraid of heights. It's good because it prevents me from jumping off anything that could potential hurt/kill me. It's also annoying because it prevents me from jumping off things that would be fun to jump off of.
    Then I have fears that are just plain weird. Perhaps my biggest fear is that I'll be driving down the road, picking my nose (which is most of the time) and I'll hit a big bump, or someone will hit me and I'll shove my finger way up my nose and end up killing my self. Apart from the usual sadness that goes along with dying, It would be a really lame way to die. You'd think it would motivate me to stop picking my nose in the car, but it doesn't.
    What about you, gentle reader, what irrational fears do you have? Double bonus points for Agoraphobia.
