In Bosnia and Montenegro there is a vampiric spirit called a tenatz that possesses a corpse and uses it as its own body. At night, it shape-shifts into a mouse and enters into a person’s home. Once inside, it waits for the victim to fall asleep and attacks, draining him of his blood. Simply burning the corpse during the day will destroy the tenatz.

A vampiric REVENANT said to exist throughout Eastern Europe, the taxim is a plague-spreading animated corpse fueled only by its desire to enact revenge. The taxim seeks out those who caused it great distress in life, and nothing short of achieving its goal will stop it.

On the Bank Islands off the coast of Australia lives a large number of people who consider themselves a type of sorcerer called a tarunga (see LIVING VAMPIRE). These individuals claim to have accumulated so much power that they are able to detach their heads from their bodies and shape-shift into invisible vampires. In this form the tarunga are able to drain away the life energy of the recently deceased, a process that takes a few weeks to complete (see ENERGY VAMPIRE). During this time, people in the community will suffer from exceptionally vivid dreams. To prevent a deceased tarunga from feeding, a watch must be maintained at its gravesite as the vampire will not feed if a person is too near.
