Dead Friend (2004)

AKA:
Ryeong

Synopsis:
"Dead Friend" aka "Ryeong" directly translates into "The Ghost".This is a 2004 South Korean horror film. It is one of a number of recent South Korean horror films set in a girls high school; the trend began with 1998's Whispering Corridors.
It starts out with
Three friends from the same high school,who are conducting a séance with a bunshinsaba - a traditional South Korean ouija board. As the spirits are called by Eun-jung, the planchette of the bunshinsaba starts jumping up and down: At the same time, her sister Eun-seo, who was sleeping in the next room, wakes up screaming. When Eun-seo comes out, she has an argument with Eun-jung about conducting the séance rather than studying. After she leaves, Eun-jung says she wishes the ghost had taken her sister away and then jumping to join her friends in bed jokingly tells them that if they don't send the ghost back it will kill them. They are all unaware of the planchette moving around the board on its own. Nor are they aware of Eun-seo being attacked by a ghostly water-based presence in the kitchen.
