Cover Story: Sleep appears to have a central role in Freud’s original model, since dreaming is considered the guardian of sleep. The function of dreaming is to protect sleep from disruption, thereby preserving its biological integrity. Freud also recognized sleep as an active process, given that human beings voluntarily withdraw from the external world to sleep. The discovery of REM sleep in the 1950s led psychoanalysts to view sleep as the necessary backdrop against which dreaming occurs. Although Freud dismissed the clinical importance of sleep disturbances, authors have since suggested that sleep disturbances might have specific psychological significance. Thanks to Freud’s work, the desire to sleep assumes an important role as a psychological, active factor that contributes to the occurrence and function of sleep. View this paper
