I am one of those people who doesn't quite know what I fear. I woke up around 3 am because of an earthquake. I woke up to the shaking, rolled over, and went back to sleep. I grew up living on the San Andreas Fault (we still live on it), so earthquakes don't really scare me. But, I've never been through a really big one. Maybe when I experience a really big one, I'll be scared.
I don't fear death. I do fear injury. Car crashes scare me. Hurricanes are pretty scary and tornadoes are too, but they are also fairly predictable (unlike earthquakes which don't scare me).
When asked what I'm afraid of, I always have two answers- bees and thunder. I'm allergic to bees, so it's only natural for me to fear them. Thunder is my one completely illogical fear, but I can't think my way out of being scared of it. I hate thunderstorms. I usually have to sit with headphones in listening to loud music or watching a loud tv show or movie. I guess I'm also scared of crazy horror movies, but I can avoid those.
