Mediums are people mediate communication between spirits of the dead and living human beings. A few ways that a psychic or medium may manifest contact with spirit may be through listening and/or hearing, sensing, seeing spirits or symbols. Some channeling signs may be change of eye color, walk, voice, out of ordinary behavior etc. Some, if not all, psychics and/or mediums possess multiple abilities naturally. They may listen to and relay messages from spirits or they can allow a spirit to control their body by speaking through it directly or by using automatic writing or drawing.
MENTAL STATE (PSYCHOLOGY) OF MEDIUMS Mediums may share similarities with people suffering from a pathological condition called dissociative or multiple personality disorder. One famous case would be Dr. Jekyll and his monstrous alter ego, Mr. Hyde.
The change of personalities is beyond conscious control, and the victim has no memory of what the secondary personality says or does. This personality may arise when in the wake of severe emotional shock of tragic experiences. The victim represses certain memories and feelings and physical symptoms such as headache, amnesia and insomnia may occur before the new personality appears.
