Bad Dream House: The family moves into an old haunted house. The walls ooze blood and talk, and even posesses the family to kill each other.
Hungry Are The Damned: The Simpsons are abducted by aliens. Lisa thinks they abducted them so they could eat them, but they were really going to send them to a planet and treat them like gods. The aliens feelings are hurt, and they let the family go.
The Raven: Lisa reads Edgar Allan Poe's tale of horror, As Homer listens, he visualizes himself as the narrator, Marge as Lenore, and Bart as the Raven. So all and all good, but that is nothing new for this series.
