Beyond the Wall of Sleep" is a short story by American writer H. P. Lovecraft written in 1919 and first published in the amateur publication Pine Cones in October 1919. Inspiration Lovecraft said the story was inspired by an April 27, 1919 article in the New York Tribune. Reporting on the New York state police, the article cited a family named Slater or Slahter as representative of the backwards Catskills population. The nova mentioned at the end of Lovecraft's story is a real star, known as GK Persei; the quotation is from Garrett P. Serviss' Astronomy with the Naked Eye (1908). The title of the story may have been influenced by Ambrose Bierce's "Beyond the Wall"; Lovecraft was known to be reading Bierce in 1919. Jack London's 1906 novel Before Adam, which concerns the concept of hereditary memory, contains the passage, "Nor...did any of my human kind ever break through the wall of my sleep. (Goodreads)
