Lejak

In Balinese mythology, a demon flying at night in the form of a head with the entrails hanging down.

They usually fly in search of pregnant women to suck blood from their babies (still in the womb or recently born). They appear in cemeteries, feed on corpses, can fly and turn into different animals (most often pigs). At the same time, during the day they look like ordinary women, but with an unusually long tongue and large fangs.
