I've come across two different videos on Youtube that show night scenes of roadblocks in Singapore. I don't have that much information about either video, but stylistically and thematically they're very similar (and very low quality). People are clowning around at a roadblock in the middle of the night, when suddenly (at the end of each video) they see a ghostly white figure. Screaming ensues. (Warning, in case you're watching these at work: The one on the right contains some cursing.)

The caption on the first video (on the left) identifies the ghost as the "pontianak". Wikipedia defines the pontianak as: a type of vampire in Malay folklore. The pontianak is usually a woman who died during childbirth and becomes undead, seeking revenge and terrorizing villages. She often appears as a beautiful woman, usually accompanied by the strong scent of frangipani. Men who are not wary will be killed when she morphs into a hideous vampire, she will also eat babies and harm pregnant women.

Wikipedia also links to a paper (which downloads as a word document) by Timothy White of the Dept. of Literature at the National University of Singapore that puts these kinds of movies in context. White notes that during the 1950s and 60s Singapore had a thriving film industry that churned out many horror films featuring the pontianak. However, these films "are all, by today’s standards, woefully unrealistic, especially in terms of the way they look." Evidently these short Singaporean ghost videos popping up on the internet must be inspired (even if unknowingly so) by that country's tradition of cheap horror flicks. The obvious fakeness of them is just part of the cinematic tradition.
