Have you ever woken up wondering, “What was that dream all about?” Maybe you were flying over a chocolate waterfall or being chased by talking dogs. Dreams can be strange, funny, or even scary—but why do they happen in the first place?When you sleep, your brain doesn’t just switch off. In fact, it becomes very active—especially during a stage called REM (Rapid Eye Movement) sleep. This is when most dreams occur. Your eyes move quickly under your eyelids, your breathing gets faster, and your brain starts creating a mini movie of memories, emotions, and imagination.One reason we dream is to help our brains sort and store all the things we saw, felt, or thought about during the day. It’s like your brain’s version of cleaning up and filing away important stuff. That’s why you might dream about school, your friends, or something you watched before bed.Some scientists believe dreams help us solve problems. Have you ever woken up with a new idea or suddenly understood something better? That might be thanks to your dreaming brain doing some quiet thinking.Dreams can also reflect your feelings. If you’re nervous about an exam, you might dream about forgetting your pencil or being late to class. That’s your brain’s way of dealing with emotions, even when you’re not awake.The truth is, scientists are still trying to understand everything about dreams. But one thing is sure: your brain is a brilliant storyteller.So the next time you dream of riding a dragon or exploring a candy castle, enjoy the adventure—your brain is doing some amazing work while you sleep!
