Witches keep male genitalia as pets
In the infamous “Malleus Maleficarum” it is said that witches steal male genitalia and communicate with them as if they were pets. They put them in nests and feed them.
The strangest thing is that this story is actually based on the Koro Syndrome when patients suddenly feel that some of their organs disappeared. It is no wonder that witches were blamed for this in the Middle Ages.
