Dreams in Color or Black and White?

Whether they’re about showing up to school in your underwear or having your teeth fall out, most dreams have one thing in common: They’re in color. 

Not for everyone, though. Roughly 12% of people dream entirely in black and white, making their nightly visions much like watching an old movie. 

That comparison isn’t a coincidence, either. The number used to be much higher: In the 1940s, 75% of Americans reported seeing color in their dreams only rarely or never, and some researchers believe that black-and-white television is part of the reason why. 

Color TV didn’t become common until the 1950s and ’60s, so for many years, most people’s most common experiences with visual stories were in gray scale.

A 2008 study found that people 25 and younger almost never dreamed in black and white, while those 55 and older who didn't have color TV in their younger years had black-and-white dreams about a quarter of the time.

 Yet the television connection is difficult to prove for certain, as are many things related to dreaming. For everything we have learned about this nightly phenomenon, scientists have still yet to conclusively determine why we dream at all.
