Description :

Mediumship is the practice of certain people—known as mediums—to purportedly mediate communication between spirits of the dead and living human beings. Several different variants of mediumship exist; the best-known forms involve a spirit allegedly taking control of a medium's voice and using it to relay a message, or where the medium simply "hears" the message and passes it on. Other forms involve materializations of the spirit or the presence of a voice, and telekinetic activity.
