Heres a weird one what body part are you most afraid of? Whatever you do, dont flash your midriff to an omphalophobe, as they are terrified of bellybuttons. In particular, they are generally more afraid of someone touching their bellybutton, or seeing another bellybutton be touched. The fear can arise from just a thought process, feeling as though someone is touching an internal part of your body, as if the umbilical cord is still attached to your organs. Or it can arise from noticing something that you perceive to be off about your own bellybutton. People can be afraid that if they allow someone to touch their bellybutton, they may pull at their umbilical cord and rip out their internal organs, causing them harm. Something that seems so obsolete on the human body can be the source of a great deal of anxiety just the thought of someone touching their bellybutton can make an omphalophobe physically sick!
