Dreams help us solve puzzles


Scientists have long wondered why we dream, with answers ranging from Sigmund Freud's idea that dreams fulfill our wishes to the speculation that these wistful journeys are just a side rapid-eye-movement, or REM, sleep. 

Turns out, at least part of the reason may be critical thinking, according to Harvard psychologist Deirdre Barrett who presented her theory in 2010 at the Association for Psychological Science meeting in Boston. She has found that our slumbering hours may help us solve puzzles that have plagued us during daylight hours.

According to Barrett, it's the visual and often illogical aspects of dreams that make them perfect for out-of-the-box thinking that is necessary to solve some problems.
"Whatever the state we're put in, we're still working on the same problems," Barrett said, adding that while dreams may have original evolved for another purpose, they have likely been refined over time for multiple tasks, including helping the brain reboot and helping us solve problems. Scientists have long wondered why we dream, with answers ranging from Sigmund Freud's idea that dreams fulfill our wishes to the speculation that these wistful journeys are just a side rapid-eye-movement, or REM, sleep.
