It manifests as the floating, disembodied head of a woman, usually young and beautiful, with her internal organs still attached and trailing down from the neck.

In the Thai film Krasue Valentine, this ghost is represented with more internal organs, such as lungs and liver, but much reduced in size and anatomically out of proportion with the head.

In Thailand, the Krasue is believed to be a cursed individual (usually a female) who engaged in various sins and fraudulent conduct during her previous life.

In recent time, the Thai entertainment industry has fictionalized the origin of Krasue as cursed from an Ancient Khmer princess, as in Demonic Beauty (2002).

This depiction, however, merely is just an attempt to put a royal touch or to reinvent a mythical beginning to a well-known story of an essentially folk origin, strictly for entertainment and commercial purpose.

There are other oral traditions that say that this spirit was formerly a rich lady that had a length of black gauze or ribbon tied around the head and neck as protection from the sunlight.

Other popular legends claim that the origin of the spirit may have been a woman trying to learn black magic that made a mistake or used the wrong spell so that her head and body became separated.

[15] អាប (Ahp/Aap), derived from a Sanskrit word आप्यति (āpyati, 'to cause anyone to suffer'),[16][17] in Cambodian folklore is usually a woman who is half spirit and half-mortal.

During the daytime, they appeared to look like normal human beings but during nighttime they ascended, leaving their mortal body with only their head and their organs, gravitating to find food.

They were believed to feast on smelly things; blood, raw meats, villager's farm animals, corpses, feces, placentas, newborns, etc.

Others believe that Ahp are black magic practitioners, borrowing a demon (evil spirit)'s power by letting them possess their body at night, as an exchange.

[19] The Krasue is under a curse that makes it ever hungry and always active in the night when it goes out hunting to satisfy its gluttony, seeking blood to drink or raw flesh to devour.

The Krasue hides the headless body from which it originates in a quiet place because it needs to join it before daybreak,[22] living like a normal person during the day, although having a sleepy look.

In the Vietnam War-era drama Freedom Deal[63] by Camerado, President Nixon orders the 1970 military incursion into Cambodia, unwittingly unleashing a legion of local ghosts similar to the Krasue.

A Krasue has been also comically featured in a Sylvania light bulb commercial for Thai audiences[69] and in a more recent dietary supplement ad.

This interpretation shows the Krasue as a woman who was abused by her husband to the point of death, being reincarnated as a ghost to enact revenge.

The Krasue lurks around an abandoned mansion, where the player acts as the role of a thief, where they must retrieve an allocated amount of money bags (depends on difficulty), before being able to leave.
