The dream functions dynamically to organize data, to reinforce memory, to resolve conflict, and to perform many of the cognitive functions of what we refer to as waking thinking during REM and NREM brain periods that occur at night. Our understanding is informed by an understanding of sleep physiology and cognitive psychology, which introduce powerful changes in contemporary psychoanalytic theory, especially the research-based conceptualization of the implicit and explicit domains of learning, memory and knowledge, and by developments in the psychophysiology of sleep and dreaming, dream-content research and neuroscience. Rather than “lost on the royal road,” perhaps paradoxically during these constructivist times, we know more about dreaming and its functions than ever before. Dreams can no longer be viewed as a royal road to the unconscious, but as a royal road to unconscious thinking. I have named this model as the organizational model of dreams.
