Why do dreams occur and what do they mean?

Dreams are like stories your brain tells you while you're sleeping, using things from your day.

When you sleep, your brain is still busy working. It takes the events and feelings from the day, like that funny joke your friend told or that scary monster in your video game, and turns them into a story while you're asleep. That's why sometimes you dream about things that happened earlier that day.

Dreams are like a peek inside your brain’s thoughts. If you had a happy day, your dream might be bright and fun, like playing with your favorite toy. If you were worried or tired, your dream might feel more wobbly or confusing, like trying to put together a puzzle with all the pieces mixed up.

Sometimes dreams even help you solve problems! It's like when you can't figure out how to tie your shoes in the morning, but during the night, your brain works it out and shows you how in your dream.
