WHY DO WE DREAM? — THE MYSTERY OF THE SLEEPING BRAIN

Every night, your brain creates an experience that can feel completely real — places, people, emotions, sounds, and stories that disappear when you wake. But why does the sleeping brain create dreams in the first place? In this episode of ORIGINS, we explore the science behind dreaming and what happens inside the brain during sleep. From the different stages of sleep to memory, emotion, brain activity, and the strange experiences that can occur while we dream, we examine what scientists know — and what remains uncertain. 🧠 WHAT YOU'LL LEARN Why humans dream What happens inside the brain during sleep The role of REM sleep and other sleep stages How dreams may relate to memory and emotion Why some dreams feel incredibly real Why we sometimes remember dreams and sometimes don't What scientists still don't know about dreaming This documentary uses scientific visualizations and artistic reconstructions to explain processes that cannot be directly seen. Some visualizations are conceptual representations rather than literal images of brain activity.
