Our brains make vivid dreams every night because they're having fun and practicing while we sleep.
Imagine your brain is like a playground, and when you’re asleep, all the kids (which are tiny parts of your brain) start playing games. These games are dreams, and they can be as simple as running around or as wild as flying with your friends on a giant swing.
Why dreams feel so real
During the day, your brain collects many different things, like what you saw, what you heard, and even how your cookies tasted. At night, it takes all these pieces and puts them together like a puzzle to make a dream. That’s why sometimes your dreams are silly or strange, they’re just mixing up parts of your day.
Dreams help the brain rest
Your brain is like a superhero that needs to take breaks. When you sleep, your brain cleans out all the extra stuff it collected during the day. It does this by having dreams, kind of like a fun way to relax and get ready for tomorrow.
