REM/awakening: Hypnopompic somatic surge
In REM sleep, hypnopompic somatic surge, loading onto the last stretch before waking near the exit toward wake. Cortical band mixed spans 6–14 Hz; acetylcholine leads, atonia state is "partial_failure", and this row's density score is 130.

Dataset readout: Hypnopompic somatic surge in REM (awakening). Cortical window 6–14 Hz (mixed). Atonia=partial_failure. Markers drive the text below — not dream-symbol meanings.
- whole-body jolt
- breath catch
- skin crawl
Transmitters in this row:
- acetylcholine
- norepinephrine
- orexin
Mechanism stack
- Hypnopompic somatic surge, loading onto the last stretch before waking sits inside REM sleep, with cortical activity running mixed at 6–14 Hz.
- Acetylcholine leads the chemistry here (cholinergic REM drive elevates cortical activation); norepinephrine, orexin also show up; density for this row is 130.
- Dataset row #10007: atonia 55/100, arousal 88/100, coherence 28/100 — the motor brake is only partial, set against a noisy, broken backdrop.
- On this awakening row the markers stack as "skin crawl" → "whole-body jolt" → "breath catch" — sharpening as arousal climbs toward the surface.
- "whole-body jolt" gets weighted as awakening body evidence for REM sleep in Lab Search — a mechanism read, not a symbol lookup.
Recall naming "whole-body jolt" in REM sleep, near the exit toward wake, gets read by the Lab as body evidence, not as a dream symbol.
Felt on waking
On waking, the marker named most often is "whole-body jolt" with "breath catch" close behind. Because this row sits at awakening in REM sleep, it lands right at the surface, sharper than anything from earlier in the night.

This row connects to Cycle timing — how episodes lengthen and shift across the night.
How Lab Search uses this row
"whole-body jolt" — 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/awakening: Hypnopompic somatic surge
This row is Hypnopompic somatic surge in REM (awakening). Cortical window 6–14 Hz (mixed). Atonia state: partial_failure. Density 130. Chart seed 10007 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.
Gauges on this page: atonia 55, arousal 88, coherence 28. Markers: whole-body jolt, breath catch, skin crawl. Transmitters tagged: acetylcholine, norepinephrine, orexin. 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.

How Lab Search should use this row
"whole-body jolt" — 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.
A note from Vigen
I am Vigen. I left REM/awakening: Hypnopompic somatic surge in the catalog because the gauges (55/88/28) plus markers (whole-body jolt, breath catch, skin crawl) are enough to be useful. If they were not, this URL would stay noindex.
