Throughout history and throughout the world, people have reported sexual contact with various supernatural creatures. Many people believe that “sex demons” were born out of the need to explain topics that are generally considered taboo. Usually, unintended pregnancy, miscarriage and promiscuity can cause anger and persecution.
In the Northern regions of Hungary, there was said to live a creature called the Liderc (or ludvérc, lucfir, or ördög depending on the region). It hatches from the first egg of a black hen and is often said to hide in people’s pockets. It enters its victims’ homes through the keyhole. Once inside, the Liderc shapeshifts into a human, often taking the form of a dead relative of the intended victim. It rapes its victim and then makes the house very dirty before departing. Some reports say that Liderc becomes attached to its victims and never leaves. The Liderc can be exorcized by either sealing it inside a tree hollow or persuading it to perform a near-impossible task, such as carrying water with a bucket full of holes. It is common even today for children in Hungary to stomp on eggs taken from a black hen or leave the eggs on doorsteps to cause mischief.
