Why do we dream and what purpose might dreams serve our brains?

Dreams are like fun stories your brain tells you while you're sleeping, helping it remember and learn things.

Imagine you’re playing with building blocks all day. When you go to sleep, your brain takes a little trip through the block tower you made, or maybe even a new one it invented! That’s like dreaming. It helps your brain practice what it learned during the day.

Your brain is like a busy librarian who needs to organize lots of books (your memories). While you sleep, it sorts through them and decides which ones are important. Sometimes, your brain even makes up new stories or mixes things together, that’s when dreams get wild!

Dreaming helps your brain stay ready for the next day, just like taking a little break after playing with blocks lets you be more creative tomorrow.
