Why Do Some People Dream in Color While Others Don’t?

Imagine your brain is like a movie theater. Some people’s dreams are like colorful movies on the big screen, while others watch them in black and white. Why? It depends on how their brains work when they’re sleeping.

The Colorful Dreamers get to see full-color dreams because a part of their brain called the visual cortex is active during sleep. The Black-and-White Dreamers might not have this same activity, so they only see shades of gray and black in their dreams.
