After a series of strange events that happened to Josh and Renai in a new house, the worst thing happens — their 10-year-old son Dalton goes into a coma and doctors don’t know how to help him. When he comes back home, the terrible events keep happening. And soon, everyone realizes that the boy is connected to another world.
Golden classic, also japanese versions of Ringu, Eye etc...
Loved the film, you might also enjoy Contagion which is along the same lines. One of my favorite scary movies and I don't usually care for horror is As Above so Below. Great for anyone who hates confined places.
and the Lawn Mower Man
