Mediumship is a form of parapsychology in which an intermediary, or medium, forms a communication link between the world of the living and the spirits of the departed. Mediums receive messages and pass them on without personal interpretation or influence. There are various ways in which they allow spirits to interact with them, but they remain in control at all times and do not become ‘possessed’ by the spirits. There are two main methods of medium communication mental and physical. See the relevant pages for an explanation of what these involve.
