1. The Number 3. Seriously, don't laugh. When I was a kid there were these ads on tv on channel 3 for the War Amps, and there'd be a kid with one leg hopping off a diving board and telling you not to play near combines. Scared the crap out of me so I would never watch channel 3 no matter what was on in case I saw one of these commercials. Unfortunately, it progressed and now I can't do anything 3 times (like knock on a door or tap my fingers or kiss my husband.) Gotta be 2 times or 4 times. Makes a lot of sense, huh?
2. Heights. Actually, I think it's more a fear of jumping than a fear of falling. You get up a few storeys, or especially on a bridge, and you think "it would be so easy to just jump off of here..."
3. Doctors. Dentists. Enough said.
4, The Absence of God. I'm not a very religious person, but I prefer to believe there's something out there besides it. It scares the crap out of me to think that there is no God, no meaning of life and when you die you're worm bait. I can't imagine the nothingness.
5. Darth Maul. You know, the red faced guy from Star Wars: the Phantom Menace. He makes me queasy.
