New research highlights a paradox in REM sleep: the brain's fuel supply appears to rise during dreaming, yet energy is still being drained. Scientists suggest that the intense neural activity behind vivid dreams may consume more energy than the increased supply can offset. The findings could reshape understanding of why sleep is restorative and how dreaming supports brain function.
