Seven people — men, women and a teen-aged girl — barricade themselves in a home located in El Cerrito, California as they spend days consulting Ouija boards. By all accounts they went insane in the process. One of the then-crazed women warned surrounding police to stay back lest her husband — then dead three months — started killing. A priest was summoned. Doors were broken down.
Largely forgotten today, the March 3, 1920 police scene in a small community just outside Berkeley, California has been described as one of the most unusual occult incidents ever investigated by California authorities. A documented case of Ouija-inspired mass hysteria, the incident generated front-page headlines, attracted the attention of medical professionals and prompted calls for reform legislation.

Edgar Cayce (March 18, 1877 – January 3, 1945) was an American attributed clairvoyant who claimed to speak from his higher self while in a trance-like state. During the sessions, Cayce would answer questions on a variety of subjects such as healing, reincarnation, dreams, the afterlife, past lives, nutrition, Atlantis, and future events. A devout Christian and Sunday-school teacher, Cayce said that his readings came from his subconscious mind exploring the dream realm, where he said all minds were timelessly connected. Cayce founded a non-profit organization, the Association for Research and Enlightenment, to record and facilitate the study of his channeling and to run a hospital. Cayce is known as “The Sleeping Prophet“, the title of journalist Jess Stearn‘s 1967 Cayce biography. Religious scholars and thinkers, such as author Michael York, consider Cayce the founder and a principal source of many characteristic beliefs of the New Age movement.

Daniel Dunglas Home (pronounced Hume; 20 March 1833 – 21 June 1886) was a Scottish physical medium with the reported ability to levitate to a variety of heights, speak with the dead, and to produce rapping and knocks in houses at will.

According to Mitch Horowitz, author of the critically acclaimed Occult America,the origins of the device known today as the Ouija Board can be traced back to the late 19th Century — although not reliably further back than that. Horowitz cites a March 28, 1886 article appearing in the Sunday supplement of the New York Daily Tribune entitled “A Mysterious Talking Board and Table over Which Northern Ohio is Agitated.” The article included an illustration and description of an early talking board very similar to today’s version.

Emanuel Swedenborg, born February 8, 1688 and died March 29, 1772, was a Swedish Christian theologian, scientist, philosopher and mystic. He became best known for his book on the afterlife, Heaven and Hell (1758). Swedenborg had a prolific career as an inventor and scientist. In 1741, at 53, he entered into a spiritual phase in which he began to experience dreams and visions, culminating in a “spiritual awakening” in which he received a revelation that opened his spiritual eyes so he could freely visit heaven and hell to converse with angels, demons and other spirits. Some describe Swedenborg as a progenitor of modern Spiritualism.
