Welcome to the Commune podcast. My name is Jeff Krasno. And this is part two of my sleep course,

the architecture of sleep, building a rhythm for rest. So the truth is, sleep actually does have

an architecture. Every night your brain builds a gothic cathedral of sorts layer by layer. It rises and falls through light sleep,

deep sleep, and REM. So inside that structure are thresholds of creativity. Einstein and

Dolly often talked about this, that theta wave state, kind of this liminal place between conscious awareness and

sleep. There are chemical cleanups that wash your brain and dreams that help you process fear

and emotion and memory. So in this episode, we're going to walk through all of those stages,

the blueprints of your night, and how

understanding them can change how you rest and dream and even wake.

This episode is part of my new sleep course on Commune.

It's a sleeper.

Over the next few weeks, we'll go deeper into each layer exploring how to work with our biology

and not against it to finally feel rested again.

So welcome to Sleep Essentials. I'm Jeff Krasno. When we talk about sleep, it's tempting to think

of it as one lengthy blackout. But sleep isn't a single state. It's more like a structure.

Each night your brain builds and rebuilds it in repeating layers, like an architect

following blueprints drawn deep into our biology.

Some of history's greatest minds were fascinated by the hidden thresholds of sleep and how

they could harvest creative problem solving there.

What did they know about sleep that we don't?

Scientists classify the different stages of sleep based on changing brainwave patterns, eye

movements, and muscle tone.
