Phobialist.com is a collection of the names and descriptions of more than 500 fears that a man named Fredd Culbertson has collected and organized. He also sells a poster-size version of the entire list that can be hung on your wall. Mr. Culbertson claims all of the phobias mentioned on his site can be found in reference books or in medical papers.

Among the unusual fears he lists:

Peladophobia: fear of bald people

Geniophobia: fear of chins

Aulophobia: fear of flutes

Paraskavedekatriaphobia: fear of Friday the 13th

Entheraphobia: fear of mother-in-law

Pteronophobia: fear of being tickled by feathers

We face many fears in this world, both real and imagined, so it isn't surprising that the most frequent biblical command is "fear not."
