A personality construct first described by Sheryl Wilson and Theodore Barber (1983, p. 340) to refer to a small percentage of the population “who fantasize a large part of the time, [and] who typically ‘see,’ ‘hear,’ ‘smell,’ ‘touch’ and fully experience what they fantasize”; such persons tend to be able to hallucinate voluntarily, to be excellent hypnotic subjects, to have vivid memories of their life experiences, and to report experiencing parapsychological phenomena.
