Episode notes
Dreams Happen Every Night
- We all dream, but most dreams vanish because the brain prioritizes memories during sleep consolidation.
- REM sleep produces most dreams and cycles every ~90 minutes, with longer REM periods toward morning.
REM Physiology And Rapid Forgetting
- REM sleep causes eye movement, higher temperature, and increased heart and breathing rates.
- Transitioning from REM to slow sleep can erase dream memory in as little as 10 minutes.

- The hippocampus consolidates memories during the night and filters what it deems important.
- Most dreams don't survive this filtering because they aren't consequential enough for long-term storage.
