In this episode an exhausted insomniac Andrew uses his sleep-deprived state of being as an excuse to do a show length rabbit trail on all his various interests regarding sleep, including biphasic sleep, sleep phases, sleep debt, sleep apnea, polyphasic sleep, the nature of dreams, and lucid dreaming. So, get your pillow and your headphones and snuggle up with a blanky and listen to the best show that ever made you yawn!
