When my son was in Kindergarten he suddenly turned into Howard Huges - washing his hands so frequently that they became raw and chaffed. I asked him about it and he wouldn't give me a good reason for doing it so I put a limit on hand washing. He then started wearing his leather baseball gloves night and day - which was weird but I allowed it at home.
About a year later he finally confessed that a librarian at his former school told his class about a girl who often chewed on her hair. Because the girl swallowed some hair in the process, it created a massive hairball in her stomach and killed her. My son then became terrified that if he swallowed even one single hair (human, cat, stuffed animal, whatever) that he would die.
