But yes, the refreshed mind, the clarity that we have after a good night's sleep isn't because we were lying down.

Our thigh muscles and liver, they don't need sleep the way we think of it.

I've transplanted livers from one person to another.

and kidneys, we don't reconnect the nerves.

I don't think sleep is really for bodily tissue.

Sleep is for the brain.

The brain makes us sleep.

And when it makes us sleep, the brain is active dreaming.

So to me, that suggests

that dreaming is a fundamental need of this collection of 100 billion neurons within our skull.

The human brain, I think brains in general, need to have the dreaming process to function best during waking life.

It's a perfect definition.

So we continue to return to the foundation of understanding I want to leave the listeners and readers with is you have waking brain and you have dreaming brain.

When you go from waking brain to dreaming brain, that's called sleep entry.

When you go from dreaming brain to waking brain, that's called sleep exit.

In the middle of it, while you're sleeping and dreaming, usually you don't know you're in the dream until the dream is done.

You wake up in the morning and go, oh, that was only a dream.

It's in the rear view.

Lucid dreaming is being in the middle of sleep, dreaming, and saying, hey, I have a little bit of, I realize I'm in a dream.

you haven't woken up, you're actually still asleep and dreaming.
