“My sister had rented a room inside the moon. The window looked down onto our old kitchen, but only when nobody was speaking.”

“Calibration clean. She asks us to leave the corridor light on.” — E. Venn, 22:41
01Threshold
N1 · hypnagogia · 7 minutes
The room lets go
one edge at a time.
Alpha rhythm thins. Muscles soften. The sleeper can still insist she was awake, though her sense of the room has begun to unfasten.
“I was carrying a glass of water up a staircase, but every step was the sound of someone turning a page.”

A silver weather
crosses the signal.
Conscious access closes. K-complexes test the perimeter; spindles briefly braid the cortex at 12–15 Hz, protecting sleep from the building around it.

The “90-minute cycle” is a useful average, not a metronome. Night 214’s cycles measured 84 / 96 / 91 / 103 minutes.

N3 · delta predominance · 71 minutes
Down here,
time has weight.
Neurons enter a vast, synchronized tide. Heart rate falls; waking becomes difficult. This is the night’s deepest maintenance window—not oblivion, but ordered quiet.
Process SSleep pressurerelative adenosine load
Adenosine accumulates while we are awake, then clears as sleep consolidates. Circadian timing decides when the door opens; pressure decides how insistently we pass through it.

The eyes begin
to read inward.
The EEG resembles waking while the body remains still. Memory, feeling, and image negotiate without the ordinary rules of address.
“A blue horse waited politely in the lift. I knew it had come to return a glove I lost when I was nine.”
“The station announced my name as a destination. Everyone got off. I stayed, because I wanted to see where I ended.”

The wolf hour
has no wolf.
Around four, body temperature nears its minimum and the night can feel unusually absolute. Old folklore gave this hour teeth. Physiology gives it a quieter explanation.
The subject surfaced for ninety-one seconds, adjusted the blanket, and returned to N2 without later recall. In the control room, the air system clicked once. Nothing entered. Nothing needed to.

the edges.
At 06:31 the sleeper opened her eyes before the lamp rose. She described the night as dreamless, then remembered the blue horse.
