Likewise, the entire audience can affect the clarity of the spirit communication at a psychic medium demonstration. If the audience as a whole is very open, accepting and light-hearted, this helps the psychic medium, as it would help any speaker on stage. If the audience as a whole is skeptical, apathetic or angry, this can negatively affect the psychic medium, as it might affect any speaker in front of such a group. Spirit communication is about energy. If the energy in the room is low, it makes it more difficult for the psychic medium to raise his or her energy to connect with spirit. If the energy is high, it can assist the psychic medium to raise his or her energy.
A widely known channeler of this variety is J. Z. Knight, who claims to channel the spirit of Ramtha, a 30 thousand-year-old man. Others purport to channel spirits from "future dimensions", ascended masters,[32] or, in the case of the trance mediums of the Brahma Kumaris, God.[33] Other notable channels are Jane Roberts for Seth, Esther Hicks for Abraham,[34] and Carla L. Rueckert for Ra.[35][36]
Humans have been fascinated with contacting the dead since the beginning of human existence. Cave paintings by indigenous Australians date back 28,000 years, some depicting skulls, bones, spirits and the afterlife.[3] Other cave paintings in Indonesia date back a further 10,000 years.[4] Mediumship gained popularity during the nineteenth century, when ouija boards were used by the upper classes as a source of entertainment. Investigations during this period revealed widespread fraud—with some practitioners employing techniques used by stage magicians—and the practice began to lose credibility.[5][6] Fraud is still rife in the medium/psychic industry, with cases of deception and trickery being discovered to this day.[7]
Modern spiritualists and psychics keep detailed files on their victims. As might be expected, these files can be very valuable and are often passed on from one medium or psychic to another when one retires or dies. Even if a psychic doesn't use a private detective or have immediate access to driver's license records and such, there is still a very powerful technique that will allow the psychic to convince people that the psychic knows all about them, their problems, and their deep personal secrets, fears, and desires. The technique is called cold reading and is probably as old as charlatanism itself... If John Edward (or any of the other self-proclaimed speakers with the dead) really could communicate with the dead, it would be a trivial matter to prove it. All that would be necessary would be for him to contact any of the thousands of missing persons who are presumed dead—famous (e.g., Jimmy Hoffa, Judge Crater) or otherwise—and correctly report where the body is. Of course, this is never done. All we get, instead, are platitudes to the effect that Aunt Millie, who liked green plates, is happy on the other side.[192]

While there are a few different forms of mediumship, I work as a mental medium, which means I communicate with spirits through the use of telepathy. Spirits impress my mind and body with thoughts and feelings that come in the form of "clairs." I mentally "hear" (clairaudience), "see" (clairvoyance), "know" (claircognizance) and/or "feel" (clairsentience) messages from spirits. I like to say that I act as the bridge between the spiritual and the physical world, with the intention of healing both worlds.

But here's the interesting part: the writing samples produced were analyzed and it was found that the complexity scores for the psychographed content were higher than those for the control writing across the board. In particular, the more experienced mediums showed higher complexity scores, which typically would require more activity in the frontal and temporal lobes--but that's precisely the opposite of what was observed.
The first documented tarot packs were recorded between 1440 and 1450 in Milan, Ferrara, Florence and Bologna when additional trump cards with allegorical illustrations were added to the common four-suit pack. These new decks were called carte da trionfi, triumph cards, and the additional cards known simply as trionfi, which became "trumps" in English. The earliest documentation of trionfi is found in a written statement in the court records of Florence, in 1440, regarding the transfer of two decks to Sigismondo Pandolfo Malatesta.[6][7]
