Pre-REM atonia ramp in N2 sleep (onset)
On the approach into sleep architecture, the marker named most often is "progressive limb heaviness" — the clearest signal for pre-REM atonia ramp, showing up before the cycle settles. Band mixed at 6–14 Hz; acetylcholine chemistry; density 127.4.

Dataset readout: Pre-REM atonia ramp in N2 (onset). Cortical window 6–14 Hz (mixed). Atonia=partial_failure. Markers drive the text below — not dream-symbol meanings.
- progressive limb heaviness
- face slackening
- eye movement precursors
Mechanism stack
- Cortically, this row runs mixed at 6–14 Hz while pre-REM atonia ramp, showing up before the cycle settles plays out in N2 sleep.
- The lead transmitter is acetylcholine (cholinergic REM drive elevates cortical activation), alongside glycine, GABA — this row's density score is 127.4.
- Dataset row #10025: atonia 70/100, arousal 28/100, coherence 66/100 — the motor brake is holding firm, set against a steady, orderly backdrop.
- On this onset row the markers stack as "eye movement precursors" → "face slackening" → "progressive limb heaviness" — building as the stage gate closes.
- The Lab treats "progressive limb heaviness" here as onset somatic evidence layered onto imagery for N2 sleep — a mechanism read, not a symbol lookup.
The Lab treats "progressive limb heaviness" as a mechanism marker when it shows up at stage entry in N2 sleep — not something to look up in a dictionary.
Felt on waking
On waking, the marker named most often is "progressive limb heaviness" with "face slackening" close behind. Because this row sits at onset in N2 sleep, it rarely stands alone in memory — it arrives merged with the drift into sleep.

This row connects to Atonia lock — the GABA–glycine brake that holds skeletal muscle offline during REM.
How Lab Search uses this row
"progressive limb heaviness" — tied here to acetylcholine activity is treated by Lab Search as a body-side input for N2 sleep, not as imagery to interpret — it changes the mechanism weighting, not the story.

How to read Pre-REM atonia ramp in N2 sleep (onset)
This row is Pre-REM atonia ramp in N2 (onset). Cortical window 6–14 Hz (mixed). Atonia state: partial_failure. Density 127.4. Chart seed 10025 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.
Gauges on this page: atonia 70, arousal 28, coherence 66. Markers: progressive limb heaviness, face slackening, eye movement precursors. Transmitters tagged: acetylcholine, glycine, GABA. 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
"progressive limb heaviness" — tied here to acetylcholine activity is treated by Lab Search as a body-side input for N2 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 Pre-REM atonia ramp 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.
