In one dream sequence, an older man is shown cutting words into a dead man's body, whilst a young boy watches, with many closeups. He then, in a closeup, pulls up the corpses eyelids with tweezers, and then cuts off the eyelids with a pair of scissors; although the eyelids do not bleed, this scene could be very disturbing.
A boy is found in the corner of a room with bloody hands. The walls are covered in bloody hand and claw marks.
A young boy is seen running throughout the house. He climbs into the dumbwaiter looking for an escape, but then somehow gets locked into the incinerator and burned alive. His burnt body is repeatedly seen in the movie.

There is a scene where a boy tears up the walls of the house, many dead bodies fall out of the walls.
