Charles Anthony Selby McCreery (born 30 June 1942) is a British psychologist, best known for his collaboration with Celia Green on work on hallucinatory states in normal people.
During the Coronation of Queen Elizabeth II in 1953 Charles McCreery was a page to Field Marshal Viscount Alanbrooke, and took part in the ceremony in Westminster Abbey.
[2] According to a survey they conducted most apparitions appear visually within three metres of the person, and the experience is usually short, lasting less than a minute in many cases.
They put forward the hypothesis that not only was the figure of the apparition hallucinatory, but the rest of the field of perception at the time as well.
McCreery later collaborated with Green on a book on lucid dreaming,[3][4][5] which discussed further the concept of metachoric experience, and added false awakenings to the category.
