There's a sort of ghost archetype in Japanese folklore of the onryo which takes the form of a stringy, black haired young woman in a white funeral gown who returns to the world of the living to seek vengeance upon those who wronged her in life. It's become a really popular thing in Japanese horror lately what with The Ring and The Grudge and the like but it's by no means a recent phenomenon
The closest approximation I can find in Chinese folklore is The Nǚ Guǐ who is, apparently, the spirit of a woman who committed suicide while wearing a red dress (ghosts in Asian folklore tend to have strangely specific origin stories for some reason) who comes back to the world of the living looking much like the young lady in this video (Why the Nǚ Guǐ doesn't come back wearing a red dress is beyond me) in order to seek vengeance on those who wronged her in life.
So yeah, Asian countries are full of the vengeful spirits of young women clad in white if their folklore is to be believed.
Not that I'm justifying these people being scared, but it is also worth mentioning that in most Asian countries white is still the funerary color (and where the more hip black has taken place, white would still be acknowledged by the psyche as THE color of death, I would assume). The equivalent of wearing all black in the West.
Doesn't it seem a little scripted?
It looks as if next person enters just after she's finished her laughing as the previous person enters the frame...or is it just cut at those places?
Genius. How are people not getting this. It's all about standing where a person least expects it.
All those people are looking at their hand and walking in at 45 degrees, then when they look ahead there's a motionless white figure on their peripheral vision.
