Overview
- The PLOS Biology study published Tuesday found that vivid dreams during stage N2 sleep made people feel they had slept more deeply.
- Researchers woke 44 adults during N2, which takes up about half the night, used high-density EEG, and sorted reports as vivid, vague, or none.
- Immersive dreams became more common later in the night and matched higher depth ratings even when EEG pointed to lighter sleep.
- A sleep scientist said EEG depth scores miss key experience, prompting calls for better objective markers and independent replication.
- The authors see a path to test dream-focused therapies for people who feel sleepless despite normal lab results.
