Why Do We Dream? (And Why You Forget Dreams So Fast)

You wake up with a vivid dream still on your mind, and within minutes it's gone. Why do we dream at all, and why does your brain delete dreams the moment you wake up? In this video, we break down what science knows, and what it's still arguing about. You'll learn how REM sleep was discovered in 1953, why dreaming happens roughly every ninety minutes, and the major ideas about why we dream: Freud's disguised wishes, the activation-synthesis theory, the threat-rehearsal idea, memory processing, and a modern theory that compares dreams to noise added when training an AI. Then we look at why dreams fade so fast, including the role of brain chemistry, the hippocampus, and why some people remember far more dreams than others. Finally, we get practical with a simple dream-catching kit: how to stay still when you wake, why a notebook beats your phone, how sleep length and alcohol affect REM, and an experiment you can try tonight. If you've ever wondered why dreams disappear, or how to remember your dreams, this one is for you.
