Triskaidekaphobia

Triskaidekaphobia is a severe and irrational fear of the number 13. European/American culture has long had a superstitious fear of the number 13 as shown by the belief that Friday the 13th is an unlucky day and the fact that many hotels do not have a 13th floor. However, at its extreme, triskaidekaphobia can be a debilitating fear that can cause a person a great deal of difficulty. Behavioral therapy can help successfully treat this phobia.
