Until recently, it was widely accepted that all people dream—except, perhaps those with certain brain injuries. However, researchers have discovered that there are some people who appear to have no dreams at all—or at least, they never remember any. While you may worry that something is wrong with your memory, research indicates there’s no connection.
“Nine percent of people will say they don’t have dreams,” says Pagel. “When we specifically question them, ‘Do you really not dream?’” most will say, ‘Well, my last dream was years ago,’ but a small number of people—2 in 1,000—say they have never ever dreamed.”
Pagel compared a group of non-dreamers to rare dreamers in a sleep lab, waking them up during various stages of sleep. About 10 percent of the rare dreamers did report having at least one dream—but the others did not.
“One was a math professor,” says Pagel. “Most of them had jobs and were very functional. There was nothing wrong with their memory, no abnormalities.”
So, if you don’t dream, don’t worry. It’s not known if people who never remember dreaming truly don’t dream, or just can never remember
