Researchers have found that playing sounds associated with unsolved puzzles during REM sleep can help lucid dreamers solve those puzzles more effectively the next day. The study involved 20 participants who signaled awareness in their dreams through eye movements and sniffs. This technique, known as targeted memory reactivation, leverages the brain's memory processes to enhance learning during sleep.
