Transmigrant

A transmigrant, or walk-in, is a possessing entity that takes over the physical body of a human host, generally for the rest of the life of the host; as distinguished from trance mediumship, where the host is temporarily usurped by the possessing entity. Our use of the term is borrowed from William S. Burroughs, who wrote of a form of transmigration in "Cities of the Red Night" (1981).

By their own accounts
The following persons claimed to be transmigrants:


 * T. Lobsang Rampa, a Tibetan lama who inhabited the body of Cyril Henry Hoskins;
 * Vivenus, a Venusian woman who possessed her own "Earth double".
