Vivid Dreams Improve Perceived Sleep

A PLOS Biology sleep‑lab study found that the immersiveness of dream experiences, not just objective sleep physiology, predicts how deeply people say they slept. Immersive REM/mentation may buffer perceived sleep depth across the night, explaining why some people feel unrested despite normal objective sleep measures. — If dream quality drives subjective sleep satisfaction, sleep medicine, workplace wellness, and public health guidelines should incorporate dream assessment and not rely solely on objective metrics.
