Many of us have a fear of something; maybe it's the fear of heights. Or how about the infamous arachnophobia -- that's not uncommon either. But have you ever heard of deipnophobia? It's the fear of dinner conversations during a social scene (I wonder if Thanksgiving at the in-laws would count).

Here's an astonishingly long list of unusual phobias you may have never heard of -- or perhaps you actually know someone who exhibits these symptoms! For example, if you know a person who breaks out in cold sweats as soon as they go inside, perhaps they'll make a quick escape because they have domatophobia. That's the irrational fear of houses, or being trapped in one. Have you ever eaten peanut butter and had it stick to the roof of your mouth? That's a fear all in itself called arachibutyrophobia.

Another one that may be slightly more common than the others on the list is paraskavedekatriaphobia -- the fear of Friday the 13th. If you couldn't pronounce that the first time, you're not alone. Some of these descriptions may sound crazy or made up. Like philemaphobia, for example, which is the irrational fear of kissing. But you can bet there's a phobia for just about everything. Check out the list for even more fears.
