Some people believe they can talk to the dead, which is called necromancy, but other people believe it is impossible. Self-proclaimed mediums profess the ability to receive messages from the dead. Some Bible scholars warn that the Bible forbids necromancy.
Modern-day mediums, including Theresa Caputo and John Edwards, perform in the presence of television audiences, selecting members of the audiences to communicate with dead friends and loved ones. Some people who wish to contact the dead utilize such practices as mirror gazing, seances and Ouija boards to establish communication.
A well-known unbeliever, Harry Houdini, famously descried the practice of talking to the dead, and offered $10,000 to anyone who could prove it to actually be possible. Some Christian leaders warn that mediums and other conjurers of the dead actually establish communication with demons instead of the dead.
