Penanggalan (Malay)
The penanggalan or penanggal is a nocturnal vampiric entity from Malay ghost myths. It takes the form of a floating disembodied woman's head, with its organs and entrails trailing from its neck. From afar, the penanggalan is said to twinkle like a ball of flame, similar to the will-o'-the-wisp phenomenon.
It is a witch that developed the ability to take such a form through meditation in a vat of vinegar. The creature is a living human being during daytime or at any time when it does not detach itself from its body. The penanggalan often hunts at night for menstruation/blood from birth. It also hunts for pregnant women and young children.
