When you enter REM sleep your eyes will move or your fists will clench, both of which can be observed on a polygraph. LaBerge did this many times before attempting to study dreams by proving first, that he could study sleep patterns and prove his subjects were asleep. He was…

The subject, a 24 year-old Caucasian female who was referred to as Brandy, took a pretest of the Self-Esteem Rating Scale (SERS) developed by Nugent and Thomas (1993) and the Body Image Avoidance Questionnaire (BIAQ) by Rosen, Srebnik, Saltzberg, and Wendt (1991) before the baseline data was collected.
