Decoding Sleep: REM, Deep Sleep, and the Neuroscience of Why We Dream

You'll spend a third of your life asleep — but do you actually know what's happening? In this episode, Albany and Grace decode the full architecture of sleep, from the brain's aggressive chemical shutdown at night to the strange paralyzed hallucination state of REM. We break down how deep slow-wave sleep consolidates memory, repairs your body, and powers a nightly "brain wash" that clears the toxic proteins linked to Alzheimer's disease. Then we dive into why we dream — moving past Freud into cutting-edge neuroscience, including the overfitted brain hypothesis and what AI teaches us about why our sleeping minds need chaos. Plus: the real science behind sleepwalking, PTSD nightmares, and what chronic sleep deprivation is quietly doing to your brain.
