Why do we selectively remember dreams? | Matthew Walker

Parent Episode: Dr. Matthew Walker on Sleep for Enhancing Learning, Creativity, Immunity, and Glymphatic System

Recalling our dreams depends on whether we are awakened shortly after the dream has occurred, which allows the brain to commit the dreamed experience to memory. Anecdotal accounts suggest, however, that dreams are already remembered – as evidenced by later recall of a dreamed experience, days or even weeks after it occurred. It's possible that these hidden, unconscious memories may have enormous effects on our conscious lives. In this clip, Dr. Matthew Walker posits his theory that dreams are not forgotten; rather, they are merely inaccessible and may have a tremendous influence on our wakeful state.
