“ [A] new finding shows that while in the 1940s, three-quarters of those surveyed claimed to dream in black and white, today, three-quarters say the opposite, that they dream in color. This reversal is attributed to a change in the number of people who grew up watching color rather than black and white television... another hint that our private dreams are intimately linked to our collective mediated experiences. ”
