A striga or properly strzyga(female) or strzygoń(male) is a kind of vampire in Slavic (and especially Polish) folklore. While still alive, the strzyga has two hearts and two souls, as well as two sets of teeth. When such a person dies, only one soul gets passed on, and the other soul causes the deceased strzyga to come alive and prey upon other living beings.
A common version of this belief says that a strzyga is an undead newborn child. Any child born dead was believed to become one if certain precautions were not met. Those undead little creatures would stalk forests at night and attack night-time travellers and people who simply wander off into the woods at night, eating out their insides.
According to many sources a strzyga has red hair, blue eyes, two hearts and talons of an owl in which it can transform to fly and seek out it’s prey.
