Episode notes
How REM Builds Dream Stories
- During REM sleep the amygdala and hippocampus pull fragments of past and present while the visual cortex constructs vivid imagery.
- The prefrontal cortex goes offline so the brain stitches random signals into bizarre storylines.
How To Remember Your Dreams
- You only remember dreams if you wake from them and give them a moment to stabilize.
- To recall dreams, wake slowly and avoid immediate distractions like grabbing your phone.
Dreams Serve Practical Brain Jobs
- Dreams likely serve multiple functions like memory consolidation and emotional processing rather than a single purpose.
- They help prioritize useful old memories to address current concerns, according to Bob Stickgold.
