REM-sleep dreaming can be experimentally guided toward specific unsolved problems and improve next-day creative problem-solving. Lucid dreamers who heard soundtracks of unsolved puzzles during REM sleep reported more dreams about those puzzles. In a post-hoc analysis, participants whose dreams were successfully biased by the sound cues solved more of the associated puzzles after waking. The study provides experimental evidence that REM dreams themselves, not just sleep-related memory reactivation, contribute to creative insight, addressing a long-standing gap in dream research that had relied on anecdotal or confounded evidence.
