Some spirits are thought to be dangerous even by people who don't necessarily believe in them. One of the scariest creatures in world mythologies is the spirit from the Slavic culture known as Kikimora. In literature, she is also known as sziszimora or szyszymora. The meaning of her name may come from the Finnish language, where “kikke mörkö” means scarecrow. No matter what the roots of the word are, it is used for a being without a body, a nightmare, or a scary spirit which disturbs people at night. Kikimora is a creature which settles in a house and doesn't want to leave - making the lives of people who live there unbearable. Kikimora is usually blamed for sleep paralysis
