Then you wake up—and most of it disappears. But why do humans dream in the first place? In this fascinating psychology and neuroscience documentary, we explore the mystery of dreams, what happens inside your brain during REM sleep, and why scientists still cannot fully agree on the true purpose of dreaming.
