Is this not communicating with the dead! or put another way ‘receiving messages from the spirit world’?
“Another way that Satan misleads people is through mediums. A medium is a person who is able to receive messages from the spirit world. A great many people, including mediums themselves, believe that these messages come from spirits of the dead…The demons actually pretend to be spirits of the dead”. (Watchtower booklet: Spirits of the dead, can they help you or harm you? page 15)
