Supernatural: 10 Most Terrifying Creatures

10. Shtriga

In Albanian mythology and folklore, a Shtriga is a vampiric witch that sucks the blood of sleeping infants at night, then turns into a flying insect to escape. She is often pictured as a woman with a hateful stare and a horribly distorted face. In Supernatural the Shtriga is a kind of witch, but has origins that lead back to Ancient Rome. This version feeds of breath, your very life force, taking your vitality and making your immunity go to hell.

Shtrigas can feed off anyone, but prefer children - yep, another one of those. It is assumed that this is because children have simply more energy than us old folk. According to Sam, Shtrigas are invulnerable to all weapons made by God and Man.

Prior to the events that take place in the show, it is implied that Sam and Dean encountered a Shtriga as children. Once John left Dean in charge of taking care of Sam while he went to hunt the creature, but when Dean went out later that night, he found a Shtriga feeding on Sam. John shot the creature, causing it to retreat and escape. When John returned for it later, she was nowhere to be found.

The old hag myth is always an eerie one, from the Evil Queen disguised as an old woman in the Grimm's Fairy Tales, to the Baba Yaga, we find them throughout history, legends and sometimes in real life.
