Why do we dream and what purpose does it serve for our minds?

Dreams are like little movies your brain makes while you're sleeping to help you learn and remember things from the day.

Your brain is working hard even when you’re asleep. It’s like a busy chef in a kitchen, cooking up all the important stuff from your day. Dreams help your brain sort out what was important and what wasn’t. If you learned something new, like how to tie your shoes or ride a bike, your dreams might show you practicing that over and over again, just like when you’re trying to learn something new at school.

Dreams also help your brain get ready for the next day. Imagine if you had too many thoughts running around in your head all at once, it would be like having a million toys to play with, and you wouldn’t know where to start! Dreams help your brain tidy up those thoughts so you can think clearly when you wake up.

Sometimes dreams are silly or even scary, but that’s okay. It's just your brain working hard to make sure you're ready for tomorrow, like getting your backpack all set before heading off to school.
