“People only dream in black and white.”

For many years, a common belief held that people experienced their dreams exclusively in black and white. This misconception largely took root in the mid-20th century, during the 1940s and 1950s, a period when black and white television and film were the predominant forms of visual media. Early surveys conducted during this time indicated that a significant portion of the population reported rarely or never seeing colors in their dreams, with one 1942 study finding over 70% of college students making such a claim.

However, scientific evidence has largely debunked this long-held notion. Modern research, particularly studies involving awakening individuals during the rapid eye movement (REM) stage of sleep when vivid dreaming occurs, reveals that the vast majority of people dream in full color. These studies show that around 70-80% of people report colorful dreams when questioned immediately after being woken during REM sleep. The dramatic shift in reported dream color directly correlates with the widespread adoption of color television and media, which became common in the 1960s and beyond.

The reason this myth persisted for so long lies in a combination of factors. The pervasive nature of black and white media undoubtedly influenced how people perceived and recalled their dreams. For generations accustomed to a grayscale visual world through their entertainment, it was easy to assume their internal dreamscapes mirrored this reality. Furthermore, some earlier research methods, which asked participants about their dreams long after waking, may have led to inaccurate recollections, with individuals potentially mistaking a forgotten or less vivid dream for one devoid of color.

Today, while the vast majority of individuals dream in color, a small percentage (around 12%) still report experiencing black and white dreams. This can sometimes be linked to specific neurological conditions, but for older generations, it may also be a lasting effect of their childhood exposure to predominantly black and white media. For instance, a 2008 study found that individuals over 55 who grew up with black and white television were significantly more likely to have grayscale dreams compared to younger generations who were raised with color media.
