* * *in occultism, a person reputedly able to make contact with the world of spirits, especially while in a state of trance. A spiritualist medium is the central figure during a séance (q.v.) and sometimes requires the assistance of an invisible go-between, or control. During a séance, disembodied voices are said to speak, either directly or through the medium. Materialization of a disembodied spirit or of a specific part of a human body can allegedly take shape from a mysterious, viscous substance called ectoplasm that exudes from the medium's body and subsequently disappears by returning to its original source. At times the medium, or a material object, appears to float in the air (levitation).
