What Is the Purpose of Sleep?

Imagine your brain is like a toy factory that runs all day. When you go to bed, the workers in the factory take a break and clean up the mess they made. That’s what sleep does, it helps your brain rest, repair, and get ready for tomorrow's work. You might even dream about things from the day before, helping your brain remember them better.
