N1/onset: Hypnagogic skin-crawl

How to read N1/onset: Hypnagogic skin-crawl

This row is Hypnagogic skin-crawl in N1 (onset). Cortical window 4.53–7.7 Hz (theta). Atonia state: N/A. Density 68.3. Chart seed 37950115 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.

Gauges on this page: atonia 35, arousal 68, coherence 43. Markers: formication-like crawl, sheet kick, shoulder shiver. Transmitters tagged: GABA, histamine, 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.

What the body is doing — not what the image “means”

On waking, the marker named most often is "formication-like crawl" with "sheet kick" close behind. Because this row sits at onset in N1 sleep, it tends to blur into whatever you were thinking about right before sleep took hold. The Lab treats "formication-like crawl" as a mechanism marker when it shows up at stage entry in N1 sleep — not something to look up in a dictionary.

1. Cortically, this row runs theta at 4.53–7.7 Hz while hypnagogic skin-crawl, arriving right at stage entry plays out in N1 sleep.
2. GABA leads the chemistry here (inhibitory tone rises across cortical and spinal targets); histamine, orexin also show up; density for this row is 68.3.
3. Dataset row #37950115: atonia 35/100, arousal 68/100, coherence 43/100 — inhibition sits at a middle setting, over an unsettled, choppy backdrop.
4. On this onset row the markers stack as "formication-like crawl" → "sheet kick" → "shoulder shiver" — stacking up right before the cycle settles.
5. The Lab treats "formication-like crawl" here as onset somatic evidence layered onto imagery for N1 sleep — scored as hardware, not metaphor.

How Lab Search should use this row

The Lab does not look up "formication-like crawl" in a symbol table — tied here to GABA activity; it uses it to weight the BODY line of your N1 reading toward mechanism. Then open Decode if you also have a plot. The plot is optional; the body line is not.

This utility will not treat Hypnagogic skin-crawl 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.
