From For Thai Survivors, The Dead Live On In Ghost Sightings:
As Thai people grapple with the physical aftereffects of December’s natural disaster, they are also dealing with another serious problem: Ghosts.For many Thais, steeped in Buddhist teachings of rebirth and even older animistic beliefs in spirits, ghosts are very real. When people die suddenly and violently, as they did in the December waves, spirits cling to their bodies and to familiar places, unsure of how to cross from the world of the living to the world of the dead, many here believe.
I remember reading, years ago, that the movie Ghost did particularly well in Thailand, because most of the population found the story plausible.
