Leyak

A Balinese figure pictured as a flying head trailing its heart, lungs and liver, said to seek out pregnant women and newborns. Miguel Covarrubias wrote in 1937 that the Balinese blamed leyaks for most of the island's troubles, sickness and death among them.

Wikipedia calls the leyak a figure of Balinese folklore: a head that flies with its entrails, including the heart, lungs and liver, still hanging from it. It is said to hunt for a pregnant woman so it can suck the blood of her baby, or for a newborn child.

Miguel Covarrubias, in Island of Bali (1937), wrote that the Balinese treated the existence of leyaks as beyond dispute. They held leyaks to blame for most of the island's troubles, sickness and death among them. Like vampires, he wrote, leyaks drink sleepers' blood and relish the innards of unborn babies, and every Balinese has stories about them.

Wikipedia's article on the krasue lists the leyak among its relatives: the ahp in Cambodia, the kasu in Laos, the ma lai in Vietnam, the kuyang and pok-pok in Indonesia, the pelasik, pelesit and penanggalan, which also occur in Malaysia, Brunei and Singapore, and the Tagalog manananggal, whose lower body comes away. The Maranao call a head-detaching creature the kalibadot, and the Visayans know it as ok-ok, ungga-ungga or wugwug.

In 2019 Kompas reported that the Balinese horror film Leak Penangkeb had reached cinema chains. In its plot, five teenagers find that an old woman's five-year illness comes from her practice of pengleakan. In 2020 the police chief of Praya told Kompas that a video of a dog buried alive as a suspected leak was a hoax, and that the animal was a pet dog.
