Why Do We Dream in Color, But Remember in Black and White?

Imagine you're dreaming of a bright red balloon floating in the sky. It’s full of color and excitement! But when you wake up, all you remember is a plain black-and-white balloon. That's because your brain works differently while you’re asleep than when you're awake. When we dream, our brains make colorful pictures, but when we remember them later, those colors fade away like a wet paintbrush on paper.
