In this episode of Sleep Essentials, we step beyond the human bedroom and into the animal kingdom to explore how different species rest, dream, and survive. From insects that pause in rhythmic waves to birds that nap mid-flight, dolphins that sleep with half their brain awake, and octopuses that dream in color, sleep reveals itself as a biological negotiation between vulnerability and protection. We also explore animal dreaming — how rats replay mazes, birds rehearse songs, dogs relive scent and memory, and what these nocturnal rehearsals suggest about learning, memory, and evolution itself. The episode closes with a simple invitation: to observe how animals rest, and to reflect on what modern life may have taught us to override — our own instincts for stillness, safety, and surrender.
