In my research on Thai spirits and possession I ran across this article on the Mae Naak.
There is no Thai who does not know Mae Naak. While mentioning her can make young children run and scream hysterically in the "Nang Naak game", mothers invoke Mae Naak's name to quiet their crying infants; otherwise, the ghost might break their necks and eat their heads with chilly sauce. The gothic tale of Mae Naak Phra Khanong has been filmed more than twenty times; moreover, every one of them is a box-office hit. Thai youths grow up watching her ghostly tale on television.
Whether Nang Naak was a real person or just a fabrication is still as mysterious as the myth itself. There is no historical evidence of her existence. However, most Thais tend to believe her story is genuine, or at least some parts are. Popular legend tells that she was born in the Phra Khanong area of Bangkok about a hundred and thirty years ago during the later period of King Rama IV (1851 - 1868) and died of childbirth complications some eighteen years later in the early part of King Rama V's regime (1868 - 1910). Others assume that she lived during the reign of King Rama III (1841 - 1851). Some believers even date her presence back to more than two hundred years ago in mid-eighteen century Ayutthaya.
