In spirituality, a medium or spirit medium (plural mediums) is an individual who claims the ability to receive messages from spirits, ghosts, or other discorporate entities, or claims that he or she can channel such entities, that is, write or speak in the voice of these entities rather than in the medium's own voice. While skeptics believe such individuals are either self-deluded or simply charlatans, popular mediums often have many followers who believe strongly in their purported abilities. Examples of popular modern-day mediums are Sylvia Brown and John Edward.
