The surprising health benefits of dreaming | Sleeping with Science

Every night when you fall asleep and start dreaming, you’re actually doing very important work! According to sleep scientist Matt Walker, dreams act like a form of “overnight therapy.” In fact, your dreams may even boost your ability to solve problems and process tough emotions that affect your waking life.

Sleep -- we spend one-third of our lives doing it, but what exactly do we get out of it? And how can we do it better? In this TED series, sleep scientist Matt Walker uncovers the facts and secrets behind our nightly slumber. Check out more episodes on TED.com: https://go.ted.com/sleepingwithscience
