Why do we dream every night when we sleep?

We dream every night because our brain is busy organizing and cleaning up information from the day.

Imagine your toy box after a long day of playing, it's full of toys, blocks, cars, and sometimes even snacks! Your brain works like a tidy helper who sorts all these things so you can find them easily tomorrow. While you're sleeping, this helper goes through everything you experienced during the day and puts it in special places in your mind.

Your brain uses dreams as one of its tools to do this job. Sometimes, you might see funny animals or fly through the sky, these are just ways your brain is sorting out things that happened to you earlier. It's like when you try to remember a game by pretending you're playing it again in your head.

Just like how you clean up your toys before bedtime, your brain also needs to clean and sort information every night. That’s why you dream every night, it helps keep your mind fresh and ready for the next day's adventures!
