In northern Europe, in the Republic of Estonia, the concept of a blood-drinking vampire was imported from the neighboring countries of Latvia, Finland, Russia, Sweden, and Ukraine. Calling this vampire a vampiir, it entered silently into a person’s home, lay on top of someone, and smothered him to death while he slept. It had the ability to shape-shift into a bat and a wolf; however, a vampiir was only active a few hours each night and was susceptible to sunlight. Like many of the vampires that lived in neighboring countries, the vampiir was killed either by burning it to ash, decapitation, or by hanging.
