mental copies of one's perceptions sometime in the past; three-dimensional colorpictures with sound and smell and all other perceptions, plus the conclusions or speculations of the individual. For example, a person who had taken LSD would retain "pictures" of that experience in his mind, complete with recordings of the sights, physical sensations, smells, sounds, etc., that occurred while he was under the influence of LSD. For further information on mental image pictures and how the mind works, read the book Dianetics: The Modern Science of Mental Health by L. Ron Hubbard. —Clear Body, ClearMind: The Effective Purification Program
