Krasue-style flying heads trailing entrails turn up in 9 belief systems, all in Southeast Asia. Living sorcerers who turn dangerous appear on every continent.

Yes, and not only in Thailand. Our data holds 32 belief systems, 44 kinds in all, that describe beings from the same family as the krasue, the krahang and the phi pop: living people who practise sorcery, flying heads, and spirits that possess people and eat their organs. The krasue-style head that detaches and flies with its entrails appears in 9 belief systems from 7 peoples: Thai, Khmer, Vietnamese, Malay, Balinese, the Dayak of Kalimantan, and Filipino. Outside Southeast Asia we found no flying heads at all.

Living people who turn dangerous through sorcery, on the other hand, turn up on every continent. 25 belief systems in this set give that origin, from the witches of the Akan in Ghana to the skin-walker of the Navajo. What differs is the body. Elsewhere these people mostly turn into animals or stay in human form. Only in Southeast Asia does the head come away from the body and fly off with the guts.

The Thai krasue, krahang and phi pop

Thai sources say the krasue lives inside a woman, often an older one. At night it floats out as a head with its entrails, seen as a ball of light, and goes to eat the organs of women who have just given birth, or of newborns. Villagers therefore stick jujube thorns under the raised floor of the house wherever there is a gap or hole, believing the krasue fears getting its guts snagged. How a krasue comes into being is not stated in the sources we checked.

The krahang is the male counterpart. The source says he is a man who practised sorcery until the magic turned on him. At night he uses a winnowing basket for wings and a rice pestle for a tail, and flies off to eat filth. Our sources give no way to ward him off.

The phi pop is closer to everyday life in Isan. People there believe a pop comes from someone who learned spells, or trained as a phi fa or phi thaen medium, and could not keep the knowledge in check, or who broke a taboo known as khalam. Some households believe it passes down the family, called pop chuea. The pop possesses a person and eats their organs until they die in their sleep, the death called lai tai, and it can never eat enough raw food. The remedy is a spirit doctor who performs a rite to catch the pop and shut it in a mong khong, a fish-trap basket.

Another source on Lao and Isan spirit belief tells the pop differently. There the phi pop is classed as a phi phet, the soul of someone who did evil in a past life or who died tragically, which makes it a ghost of the dead. The first source says the pop is a living person who learned spells. The two sources disagree, and we do not decide which is right.

The krasue's relatives across Southeast Asia

All 9 flying-head beliefs share one picture: a human head with guts or organs hanging below it, out hunting at night. 7 of the 9 say it is a woman, and 7 of the 9 say it hunts pregnant women, women in labour or babies. Khmer sources say the ahp is a woman whose black magic failed until the curse rebounded on her, or who let an evil spirit possess her at night in exchange for power. The ahp drinks the blood of pregnant women and eats placentas, babies and corpses, so Khmer households lay thorny branches around the house, bury the placenta deep and far from home, and keep dogs on guard.

The Malay call it the penanggalan, a living person, usually a woman, who learned black magic until she could take her head off. The head flies with its entrails dangling and drinks the blood of women giving birth until they bleed to death. The defences come in layers: thorny mengkuang pandan around the house, pineapples planted under the floor, scissors or a betel knife under the pillow, and if you find the body left behind, turn it over. The Philippines has the manananggal, a woman who detaches her upper half and sprouts bat wings, then uses a long tongue to suck the unborn child from the womb. Villagers hang garlic at doors and windows and sprinkle salt on the lower half, which then cannot rejoin and dies at sunrise. The name comes from tanggal, 'to remove or separate', the same word as in the Malay penanggalan.

In Bali the leyak is a person who trained in Aji Pengeleakan. By day an ordinary person, by night the head and guts come loose and fly off to suck the blood of unborn or newborn babies; it also eats corpses and can become a pig. The Dayak of Kalimantan have the kuyang, someone who learned black magic for immortality or power, uses kuyang oil, and passes it down the family. Meeting a kuyang's eyes is said to bring a difficult birth. The Indonesian source compares the kuyang with other spirits of the same islands, such as the poppo of Sulawesi, the palasik of Sumatra and the selak of Lombok.

Vietnam is a little different. The ma lai is a person who becomes a ghost at night, reduced to a woman's head with organs hanging below. But the source does not say it hunts women in childbirth; it says it goes out to eat excrement and pull out entrails. In the legends of peoples in north-western Vietnam, the ma lai is a female night ghost hungry for flesh. Looking at the defences, 3 belief systems use something thorny: Thai jujube thorns, Khmer thorn branches and Malay thorny pandan.

Spirits that are kept and handed down

The inherited pop chuea has close relatives in Malay, Javanese, Batak and Filipino belief: 7 kinds across 4 belief systems, all spirits kept by an owner who puts them to work. The Malay pelesit is a familiar kept by a person, usually a woman, fed with blood from the owner's fingertip every full-moon night and handed down as an inheritance the Malay call saka. The hantu raya must also pass to an heir, and if it is not fed it turns on its owner. The Batak begu ganjang, the 'long ghost', grows taller the longer you stare, leaves blue bruises on its victim's neck, and is used by the Batak to explain mysterious illness and sudden death.

Another line keeps spirits for money. The Javanese tuyul comes from a baby that was never born or that died; its owner sends it to steal money, a kind of illegitimate wealth the Javanese call pasugihan. Historians link the belief to the income gap between farmers and traders, and the word tuyul became popular around 1929, during the Depression. Malay borrowed the word as toyol. To guard against a toyol, the source says, leave toys or mung beans near your money to keep it distracted, or keep a climbing perch in a fish tank. Our notes compare the toyol to a malevolent version of the Thai kuman thong.

Is there anything like it outside Southeast Asia?

Of the 32 belief systems, 19 lie outside Southeast Asia, and nearly all of them describe living sorcerers rather than flying heads. In Africa, the Akan of Ghana believe most witches are women who band together in the spirit world and attack only members of their own family; the abosom can expose them. The Swazi believe the ancestors punish but do not kill: death comes from evil-doers called batsakatsi. The Zulu have the lightning bird, a blood-drinking familiar of a witch that passes from mother to daughter.

In the Americas, the Aztecs had the nahualli, a person who could turn into their own animal counterpart. The Navajo have the skin-walker, a witch who turns into or disguises as an animal, but the community rarely discusses it with outsiders, so the source records only that it exists. Haitian Vodou has the lougawou, people who join night-time sorcery rites and eat human flesh, and the sousè, a kind of lougawou that draws people's blood from the corner of a house without going inside. In the Andes, 3 belief systems, Inca, Quechua and Aymara, describe the same figure, the pishtaco, who cuts victims' throats to take their fat.

In Europe and northern Asia, Slavic belief counts sorcerers among the dead who become the upyr, a corpse that rises to drink the blood of people and cattle and must be staked through with aspen and burned. The Sakha, or Yakuts, believe the souls of sorcerers and of people who died early or unnaturally become the üör. In the past they were shut in a birch-bark vessel on the roof beam of the tent and fed from time to time, much like shutting a pop in a mong khong. As for the Neuroi who turned into wolves for a few days each year, we know of them only through Herodotus, who passed on what Scythians and Greek settlers in Scythia told him, and he wrote himself that he did not believe it.

This part of the data holds nothing from Burma, China or India. Beliefs with large bodies of scripture, such as Buddhism, Hinduism and Chinese religion, get more detail in the sources than others. But if a country is missing from our data, that does not mean it has no spirits of this kind, only that the sources we checked did not record them.

When the belief points at a neighbour

What sets this group apart from ghosts of the dead is that the people believed to be them are still alive, and several sources talk about what happened to real people. The source on the pop records the anthropological explanation that the belief works as a mechanism of distrust within a community, and that people accused of being a pop were driven out. The Swazi have a diviner, the tangoma, name where a death came from. The Akan have had anti-witchcraft movements. And the Andean pishtaco story is tied to the colonial era, when conquistadors were said to use fat from Indigenous corpses on their wounds, and later to the eras of railway building and mining. We report this as the sources give it, and do not say who is or is not one.

What they really share

Across all the continents, these beings are usually someone close by, not a stranger. Akan witches harm only their own families. The pop chuea, the kuyang, the pelesit, the hantu raya and the Zulu lightning bird are all handed down within a lineage. And they are often used to explain deaths with no visible cause, from the pop's victims who die in their sleep, to the sudden deaths the Batak blame on the begu ganjang, to the deaths the Swazi attribute to the batsakatsi rather than to the ancestors. The remedy looks alike too: a specialist has to deal with it, such as the spirit doctors of Thailand and Laos, the yuta of Ryukyu, the Zulu sangoma and the Swazi diviner.

Not what you might expect

In the Thai source the pop is someone from the same community, but the Andean pishtaco is an outsider: the source says he is often a white or mixed-race man. And the flying head that the source says eats excrement is the Vietnamese ma lai. On the Thai side, the one that eats filth is the krahang, while the krasue eats the organs of new mothers and babies.

Back to the jujube thorns

If you ever heard older relatives talk about jujube thorns under the house, Khmer and Malay households have the same thing, thorny branches and thorny pandan around the house. The only difference is the name of the spirit they fear: the ahp and the penanggalan.

Frequently asked

Where does the krasue come from?

The Thai sources we checked say only that the krasue lives inside a woman, often an older one, without saying how it arises. Its relatives next door are clearer: the Khmer ahp is a woman whose black magic failed and rebounded on her, and the Malay penanggalan, the Balinese leyak and the Dayak kuyang are people who learned black magic.

What is the krasue afraid of?

Thai sources say the krasue fears snagging its guts on thorns, so villagers put jujube thorns under the house. Khmer households use thorny branches against the ahp, Malay households plant thorny pandan around the house and pineapples under it against the penanggalan, and Filipinos use garlic and salt against the manananggal.

What causes a phi pop?

People in Isan believe a pop comes from someone who learned spells, or trained as a phi fa or phi thaen medium, and could not keep it in check, or who broke a khalam taboo. Some households believe it runs in the family as pop chuea. But another source on Lao and Isan belief classes the phi pop as a phi phet, the soul of someone evil in a past life or who died tragically. The two sources disagree.

What is the phi pop afraid of?

Our sources do not name anything the pop fears. They only give the way to deal with it: a spirit doctor performs a rite to catch the pop and shuts it in a mong khong basket.

What is the difference between the krasue and the krahang?

The krasue lives inside a woman and floats out as a head with entrails to eat the organs of new mothers or babies. The krahang is a man whose sorcery turned on him; he flies with a winnowing basket for wings and a pestle for a tail, and eats filth.

What is the krasue called in other countries?

In our data the Khmer call it the ahp, the Vietnamese the ma lai, the Malay the penanggalan, the Balinese the leyak, the Dayak of Kalimantan the kuyang, and Filipinos the manananggal, which detaches its whole upper half rather than just the head.

Does the krasue eat excrement?

The Thai sources we checked say the krasue eats the organs of women after childbirth or of babies, and do not mention excrement. The one that eats filth is the krahang, and the flying head the source says eats excrement is the Vietnamese ma lai.

Are the krasue and the phi pop real?

Mythsensus does not judge whether spirits exist. What we can say is that krasue-type beliefs appear in 9 belief systems from 7 peoples in Southeast Asia, and that the source on the pop records the anthropological explanation that the belief works as a mechanism of distrust within a community.

How we counted: 370 traditions from every continent, living and ancient, from sources in dozens of languages. One tradition, one vote, and only where a source confirms it. A tradition missing here is not evidence it lacks the belief, only that we found no document. Scriptural religions (Buddhist, Hindu, Chinese, Jewish, Christian, Muslim) are described in more detail than oral ones, and some records come through missionaries or outsiders.
