I actually have a few common fears....
heights, the dark, rats and mice, baby rabbits (they look so disgusting), the night(kind of goes with the dark), Scary movies, cockroaches, big spiders like tarantulas, and big caterpillars.
Yeah I know, some of you might call me a big baby, but that's just what I grew up with. I slept with a nightlight until 7th grade, and I stopped after my friends came over and saw it....
So actually, I'm scared of any living thing that's small enough to be squished, but big enough to make a horrible, disgusting mess

.
Don't even tell me to overcome my fear of rats and mice, never.
The darkness is probably one of my biggest fears, the fact that I can't see anything and that anything can happen to me freaks the hubbajeebies out of me. Then the night, filled with kidnappers and sexual predators, that stuff.
The baby rabbits had stuck with me since I was 5, when I had a pet rabbit. The rabbit had babies, they were hairless and squirming around, it looked so disgusting. Then, I saw the rabbit eat one of her babies(which is very very nasty), and from that moment on I have some kind of fear of baby rabbits now.
Heights have always been a problem with me. From the monkey bars to the really tall tree, I just can't seem to go any higher than 4 feet. I tried climbing a tree, I always had a feeling the branch was going to break. Rock climbing in gym class, I just couldn't trust my belayer and only went half way. But I'm not afraid of roller coasters though, they're always fun.
Just wanted to confess my deepest most darkest fears... mainly cause I'm extra hyper from an energy drink and I can't seem to sleep.
