The first story of the first episode of the long running "Treehouse of Horror" series of Simsons Halloween specials.

The Simpsons move into an old house, wondering why it was so inexpensive. Their questions are soon answered when the walls begin to bleed and objects begin to fly through the air.

Marge wants to leave, but Homer tells her to sleep on it first. That night, the house possesses Homer and the kids, making them chase each other with axes and knives.

Marge intervenes and confronts the house, demanding that it treat them with respect while they are living there. The house thinks it over, and opts to destroy itself instead.

This is based on The Amityville Horror murders.
