THE FACTS

In an age of high-definition television and vivid cinematography, it might seem peculiar to think that anyone would experience colorless dreams.

For many people, the dream state can be the most turbulent, emotionally intense part of the day. Falling, flying, failing exams and being chased are among the most frequently reported themes when people are asked in studies to describe their dreams. And yet for a small segment of the population, drifting off at night means reverting to a world of monochromatic hues.

Childhood exposure to black-and-white television seems to be the common denominator. A study published this year, for example, found that people 25 and younger say they almost never dream in black and white. But people over 55 who grew up with little access to color television reported dreaming in black and white about a quarter of the time. Over all, 12 percent of people dream entirely in black and white.
