About this episode
In this episode of the Commune Podcast, Jeff explores the architecture of sleep — the repeating nightly cycles that carry us from light sleep into deep restoration and vivid REM dreaming. He breaks down N1, N2, and N3 sleep, explains why deep sleep is essential for physical repair and immune function, and describes how REM helps us process emotion, creativity, and memory.
Along the way, Jeff highlights the science behind hypnagogia — the imaginative threshold between waking and sleep that inspired minds like Einstein and Dalí — and how understanding these stages can help you wake with more clarity and ease.
Whether you struggle with groggy mornings, restless nights, or inconsistent energy, this episode offers a clear and grounded roadmap for understanding your sleep patterns — and aligning your life with the rhythms your body already knows.
