Psychic Exploration: A Challenge for Science (1974) – Edgar D Mitchell

If the British have achieved pre-eminence in producing good mediums, it is probably because of the Spiritualist organisations that have nurtured them. 

In London the British College of Psychic Science, the College of Psychic Studies and the Spiritualist Association of Great Britain are representative organisations through which inquirers into survival and other psychic questions can book a sitting with a medium.  Many also freelance from their homes.

from the  'Collection of College of Psychic Studies'.

Among the best known of today’s mediums who still use trance are Ena Twigg and Douglas Johnson. 

Most of their sittings, however, are given in waking clairvoyance.
Johnson has worked extensively with parapsychologists in England, the United States and Israel, but little of this experimental work has been published.
In experiments for W G Roll at the Psychical Research Foundation in Durham, North Carolina, Johnson scored more ‘hits’ about people when they were present than when doing absent psychometric readings.  In investigating a ‘haunted house’, Johnson was able to describe accurately the entities that the occupants of the house had reported earlier.

And in experiments at the Maimonides Dream Laboratory in Brooklyn, Johnson was able to dream telepathically about a distant art print target.

In my own experiments with Johnson, in which he tried to predict events in my future, a number of detailed predictions were fulfilled.

As with many psychic sensitives, Johnson frequently receives visual symbolic images, which he must interpret, although at other times he receives impressions in words – so called clair-audience.

Some readers may recall a filmed trance sitting in the 1966 ABC-TV production ‘The Baffling World of ESP’ on which a woman sitter was so overcome by the information Johnson’s trance control, Chiang related about her deceased father that she broke into tears.  The sitter, a London psychiatrist told me she had never met Johnson before.

Psychic magazine:  Psychics 1972 - Johnson, Douglas (ca. 1909-1988)

Modern British medium who investigated haunted houses in the United States and who appeared on television programs to demonstrate clairvoyance and psychometry. He was born in London, and his powers were evident as early as age six. His parents were not psychic but did not disapprove of his predictive talents; they permitted him to attend a Spiritualist public meeting at age 12. Three years later he went into trance for the first time, channeling information and advice to a circle of people.

In World War II he served with the Royal Air Force, but he was removed from active duty after an injury at the end of the war. He had corresponded with the College of Psychic Science (now the College of Psychic Studies ) in London and afterward gave many clairvoyant sittings there. He also spent time in the United States, where he worked with W. G. Roll, Eileen Garrett, Thelma Moss, Stanley Krippner, and other parapsychologists. He died in October 1988.
