Cautionary tales that the board opens a door to evil spirits turn the game into the subject of a supernatural dare, especially for young people. Notable users Literature Ouija boards have been the source of inspiration for literary works, used as guidance in writing or as a form of channeling literary works. As a result of Ouija boards' becoming popular in the early 20th century, by the 1920s many "psychic" books were written of varying quality often initiated by ouija board use. Emily Grant Hutchings claimed that her novel Jap Herron: A Novel Written from the Ouija Board (1917) was dictated by Mark Twain's spirit through the use of a Ouija board after his death. Pearl Lenore Curran (1883–1937), alleged that for over 20 years she was in contact with a spirit named Patience Worth. This symbiotic relationship produced several novels, and works of poetry and prose, which Pearl Curran claimed were delivered to her through channelling Worth's spirit during sessions with a ouija board, and which works Curran then transcribed. Much of William Butler Yeats's later poetry was inspired, among other facets of occultism, by the Ouija board.

In 1982, poet James Merrill released an apocalyptic 560-page epic poem titled The Changing Light at Sandover, which documented two decades of messages dictated from the Ouija board during séances hosted by Merrill and his partner David Noyes Jackson. Sandover, which received the National Book Critics Circle Award in 1983, was published in three volumes beginning in 1976. The first contained a poem for each of the letters A through Z, and was called The Book of Ephraim. It appeared in the collection Divine Comedies, which won the Pulitzer Prize for Poetry in 1977. According to Merrill, the spirits ordered him to write and publish the next two installments,
