MediumshipMediumship is the practice of purportedly mediating communication between familiar spirits or spirits of the dead and living human beings. Practitioners are known as "mediums" or "spirit mediums". There are different types of mediumship or spirit channelling, including séance tables, trance, and ouija. Belief in psychic ability is widespread despite the absence of objective evidence for its existence. Scientific researchers have attempted to ascertain the validity of claims of mediumship.
SpiritualismSpiritualism was a social religious movement in the nineteenth century, according to which an individual's awareness persists after death and may be contacted by the living. The afterlife, or the "spirit world", is seen by spiritualists not as a static place, but as one in which spirits continue to evolve. These two beliefs—that contact with spirits is possible, and that spirits are more advanced than humans—lead spiritualists to the belief that spirits are capable of providing useful insight regarding moral and ethical issues, as well as about the nature of God.
GhostA ghost is the soul or spirit of a dead person or non-human animal that is believed to be able to appear to the living. In ghostlore, descriptions of ghosts vary widely, from an invisible presence to translucent or barely visible wispy shapes to realistic, lifelike forms. The deliberate attempt to contact the spirit of a deceased person is known as necromancy, or in spiritism as a séance. Other terms associated with it are apparition, haunt, phantom, poltergeist, shade, specter, spirit, spook, wraith, demon, and ghoul.
ParanormalParanormal events are purported phenomena described in popular culture, folk, and other non-scientific bodies of knowledge, whose existence within these contexts is described as being beyond the scope of normal scientific understanding. Notable paranormal beliefs include those that pertain to extrasensory perception (for example, telepathy), spiritualism and the pseudosciences of ghost hunting, cryptozoology, and ufology.
SpiritismSpiritism (spiritisme; espiritismo), spiritist doctrine, Kardecism or Kardecist spiritism is a spiritualistic and reincarnationist doctrine established in France in the mid-19th century by the author and educator Allan Kardec (pseudonym of Hippolyte Léon Denizard Rivail). It explains, from a Christian perspective, the cycle by which a spirit supposedly returns to material existence after the death of the old body in which it dwelled, as well as the evolution it undergoes during this process.
