We dream every night, but we often can't remember those dreams. Some mornings, we recall vivid details, and other days, we piece together hazy outlines. But what about color? Do most people dream in color or in black and white?

Some people may be surprised to learn that this has proved a divisive question. Modern research has indicated that television and films have a lot to do with how we experience dreaming and what we can remember when we wake up.
