Why do we dream every night and what purpose does it serve?

We dream every night because our brain is working hard to make sense of everything we learn and experience during the day, just like how you sort your toys before bedtime.

Dreams are like little movies that play while you're asleep. Your brain uses these movies to practice what it learned, like when you try out different ways to build a tower with blocks or remember where you put your favorite toy.

Your brain is always busy, even when you’re not playing. When you sleep, especially during deep sleep, your brain goes through all the things you did that day and picks out what’s important. It uses dreams to help you understand better and remember longer, just like how you might draw a picture of your favorite game so you can tell someone about it later.

Your brain needs time to rest and work on these problems, which is why we dream every night. It’s like cleaning up your room every day so you can play better tomorrow. Dreams help your brain stay sharp and ready for new adventures!
