No one knows for sure! When you go to sleep your brain cells don’t switch off, they keep firing just in different ways. So dreams are just bits of brain activity that are happening when you’re not awake to control them.

Dreaming might help our brains take in all of the new things that happen every day, especially tricky tasks that involve moving and thinking lots. They might also give us time to forget the things we don’t need to remember!

But some scientists think they might just be an accident, and that there’s no real reason for them
