short for mental image pictures, 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, if a person was in a car accident, he would retain "pictures" of that experience in his mind, complete with recordings of the sights, physical sensations, smells, sounds, etc., that occurred during that incident. —9th ACC Volume 1 Approved Glossary
