Why Do We Dream?
Everyone dreams, but scientists can’t figure out why. Here are two different explanations.

“We have a different theory. We believe that dreams might be images in our minds. The brain ‘cleans out’ unused information when we dream.”
Both ideas make sense, but for now there’s no proof for either one. The only way to solve this mystery is to do more research and collect data.
