REM/fragmentation: Hypnopompic somatic surge
Dataset row #54391458 frames hypnopompic somatic surge, showing up in short, interrupted bursts — acetylcholine + adenosine + norepinephrine against arousal 81/100 and coherence 32/100.

Dataset readout: Hypnopompic somatic surge in REM (fragmentation). Cortical window 3.95–10.51 Hz (mixed). Atonia=partial_failure. Markers drive the text below — not dream-symbol meanings.
- breath catch
- micro-arousal body hitch
- skin crawl
Transmitters in this row:
- acetylcholine
- adenosine
- norepinephrine
Mechanism stack
- REM sleep frames hypnopompic somatic surge, showing up in short, interrupted bursts, against a mixed trace of 3.95–10.51 Hz.
- Chemistry is acetylcholine-led here (cholinergic REM drive elevates cortical activation), with adenosine, norepinephrine co-listed; density 114.8 on this row.
- Dataset row #54391458: atonia 50/100, arousal 81/100, coherence 32/100 — inhibition sits at a middle setting, against a jagged, low-coherence backdrop.
- On this fragmentation row the markers stack as "skin crawl" → "micro-arousal body hitch" → "breath catch" — landing as separate bursts instead of one continuous run.
- "breath catch" gets weighted as fragmentation body evidence for REM sleep in Lab Search — a mechanism read, not a symbol lookup.
For REM sleep during fragmentation bursts, "breath catch" is exactly the kind of detail the Lab weights over plot — mechanism before meaning.
Felt on waking
On waking, the marker named most often is "breath catch" with "micro-arousal body hitch" close behind. Because this row sits at fragmentation in REM sleep, it resists being told as one memory — expect fragments, not a narrative.

This row connects to Cycle timing — how episodes lengthen and shift across the night.
How Lab Search uses this row
"breath catch" — tied here to acetylcholine activity is treated by Lab Search as a body-side input for REM sleep, not as imagery to interpret — it changes the mechanism weighting, not the story.

How to read REM/fragmentation: Hypnopompic somatic surge
This row is Hypnopompic somatic surge in REM (fragmentation). Cortical window 3.95–10.51 Hz (mixed). Atonia state: partial_failure. Density 114.8. Chart seed 54391458 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.
Gauges on this page: atonia 50, arousal 81, coherence 32. Markers: breath catch, micro-arousal body hitch, skin crawl. Transmitters tagged: acetylcholine, adenosine, norepinephrine. Those fields are why two “similar” titles are not duplicates. If a marker did not happen to you, say so — do not wear the whole row.
What the body is doing — not what the image “means”
On waking, the marker named most often is "breath catch" with "micro-arousal body hitch" close behind. Because this row sits at fragmentation in REM sleep, it resists being told as one memory — expect fragments, not a narrative. For REM sleep during fragmentation bursts, "breath catch" is exactly the kind of detail the Lab weights over plot — mechanism before meaning.

How Lab Search should use this row
"breath catch" — tied here to acetylcholine activity is treated by Lab Search as a body-side input for REM sleep, not as imagery to interpret — it changes the mechanism weighting, not the story. Then open Decode if you also have a plot. The plot is optional; the body line is not.
This utility will not treat Hypnopompic somatic surge as a spirit, a pregnancy test, or a death omen. It will treat it as a stage-bound somatic metric. If symptoms are nightly, worsening, or include dream enactment, that is clinical, not catalog.
