In Indonesian mythology, a sundel bolong, is a mythical ghost from the archipelago which is a woman with beautiful long black hair and a long white dress (her form is similar to Pontianak).
The name "sundel bolong" derives from the physical appearance of the ghost.
Modern folklore studies believe that the myth was developed in Javan culture to deter prostitution that developed during the Dutch East Indies colonization.
In folklore, a sundel bolong, more commonly referred to as a prostitute ghost is the soul of a woman who died when she was pregnant outside of marriage and therefore gave birth in her grave, or who died during childbirth and the baby came out from her back (this is the reason why the hole was created in her back)[1] which is concealed from men by her long black hair.
The victims of sundel bolong consist mainly of men and children.
