Ophidiophobic: Afraid of snakes.
I have been afraid of snakes since I was five years old. While we were on vacation in Florida, my parents took me to the zoo in Miami, including the Reptile House. That night, in our hotel, I had nightmares about snakes, and woke up screaming. A few months later, we came home from some outing to discover what, at the time, seemed to me a HUGE black snake, curled up on our front porch. I refused to get out of the car until my father got it off the porch and out of our yard.
My most up close and personal experience with snakes came when I was eight years old. It was summer, and I was walking through a tobacco field with one of my cousins. Her father, my Uncle Bill, came up beside us with a hoe and, before we knew what was happening, he had cut the head off a copperhead that was mere inches from my leg.
Since that time, I've had a completely irrational fear of any and all snakes. I can't even stand to see them on television (which means I cringe several times an episode while watching Survivor!). I decided to tempt fate by watching Snakes On A Plane with the rest of the family a few years ago....and wound up hallucinating snakes on our living room floor by the time it was over!
I've had other irrational fears in my life, but this is the only one that has been around this long--I have a feeling I'm going to be dealing with it for the rest of my life.
