Have you ever heard of growing eyelashes on your gums? It's an actual condition that some people have. It's super rare, with only five known cases in history, and doctors believe that it's to do with a hormonal effect that results in hair growing in the gums.
I've also never heard of the Jerusalem Syndrome or many of these other conditions that some people experience. They're all really rare but also very interesting.
