"H. P. Lovecraft's Dreams in the Witch-House" is the second episode of the first season of Masters of Horror, directed by Stuart Gordon.

It is adapted from the short story "The Dreams in the Witch House" by American horror author H. P. Lovecraft.

Initially ignoring the pain, he becomes horrified when she transforms into an old witch and laughs devilishly as he screams in horror, making him wake up outside of Frances's room.

Walter then finds himself seated in front of an open book that he has bled on in the restricted access room of a library in Miskatonic University, in which he sees diagrams of unearthly geometry and rituals for infant sacrifice.

Walter breaks through the wall in his attic room where the witch and rodent came through and finds the skeletons of past sacrifices.

The cloaked witch places a silver dagger into Walter's hand and commands him to kill Danny.

This leads to a struggle where she steals the knife, but Walter is able to gouge her eyes out with his hands, and then strangle her with the crucifix.

The manager and the police arrive and the former opens the door with his service keys to find Walter covered in blood, holding Danny's corpse.

The police recover the infant remains, some dating back 300 years, the knife, and unknown DNA from the bite wounds on Danny's neck.

It also sets the story in contemporary times, updating small details while remaining relatively faithful to the original plot.

For example, whereas in the Lovecraft story the protagonist is a student of quantum mechanics, in the television adaption he studies string theory.

The TV adaptation features the rat-like creature with a human face, Brown Jenkin, from Lovecraft's original tale, and also the witch Keziah Mason.
