Automatic writing or psychography is an alleged psychic ability allowing a person to produce written words without consciously writing. The words are claimed to arise from a subconscious, spiritual or supernatural source.
Automatic writing as a spiritual practice was reported by Hyppolyte Taine in the preface to the third edition of his De l'intelligence, published in 1878. Besides "etherial visions" or "magnetic auras", Fernando Pessoa claimed to have experienced automatic writing. He said he felt "owned by something else", sometimes feeling a sensation in the right arm that he claimed was lifted into the air without his will. George Hyde-Lees, the wife of William Butler Yeats, also claimed that she could write automatically.
William Fletcher Barrett wrote, "Automatic messages may take place either by the writer passively holding a pencil on a sheet of paper, or by the planchette, or by a 'ouija board'." In spiritualism, spirits are claimed to take control of the hand of a medium to write messages, letters, and even entire books. Automatic writing can happen in a trance or waking state.Arthur Conan Doyle, in his book The New Revelation (1918), wrote that automatic writing occurs either by the writer's subconscious or by external spirits operating through the writer. The Surrealist poet Robert Desnos claimed he was among the most gifted in automatic writing. Some psychical researchers such as Thomson Jay Hudson have claimed that no spirits are involved in automatic writing and that the subconscious mind is the explanation.
Alleged cases of automatic writing have included Jane Roberts,Helen Schucman and Neale Donald Walsch. In 1975, Wendy Hart of Maidenhead claimed that she wrote automatically about Nicholas Moore, a sea captain who died in 1642.
