10. Fear of Buttons (Koumpounophobia)

Yep, this is one the unusual phobias, too. People who suffer from koumpounophobia can’t stand the sight, touch, or smell of buttons. (Who knew buttons even had a smell? People who suffer from koumpounophobia, that’s who!) Some sufferers even need to wash their skin if it comes into contact with a button. In more extreme cases, some people can’t say or write the word ‘button.’
11. Fear of Bald People (Peladophobia)

Fearing bald people can often be attributed to a childhood trauma involving someone with no hair. It could be as innocent as seeing scary Uncle Fester from The Addams Family movies, or a tabloid shot of Britney Spears after she went crazy and shaved her head. But on a more serious note, it can also be caused due to a heartbreaking incident, such as witnessing someone’s hair falling out due to an illness.
12. Fear of Strings (Linonophobia)

Linonophobia refers to the fear of strings. It doesn’t have to be anything, like what’s seen in this image above. Any kind of strings really trigger this fear, you name it; guitar strings, balloon strings, etc. Symptoms typically include extreme anxiety, dread, shortness of breath, irregular heartbeat, sweating, dry mouth, shaking and so on.
13. Fear of Peanut Butter (Arachibutyrophobia)

The fear of peanut butter isn’t as irrational as some might think, and this isn’t someone who’s simply got a severe peanut allergy. Arachibutyrophobia is actually rooted in the fear of having it stick to the roof of your mouth. More generally, it can be related to a fear of choking or sticky textures.
This fear can often be traced to an early tragic event, such as seeing someone have an allergy attack from peanut butter as a child.
