The Dreams in the Witch House
From The Art and Popular Culture Encyclopedia
"The Dreams in the Witch House" is a short story by H. P. Lovecraft, part of the Cthulhu Mythos genre of horror fiction. Written in January/February 1932, it was first published in the July 1933 issue of Weird Tales.
"The Dreams in the Witch House" was likely inspired by the lecture The Size of the Universe given by Willem de Sitter which Lovecraft attended three months prior to writing the story. Several prominent motifs—including the geometry and curvature of space, and a deeper understanding of the nature of the universe through pure mathematics—are covered in de Sitter's lecture. The idea of using higher dimensions of non-Euclidean space as short cuts through normal space can be traced to A. S. Eddington's The Nature of the Physical World which Lovecraft alludes to having read (SL III p 87).
