REM/fragmentation: Fragmented REM with micro-arousals
Fragmented REM with micro-arousals, scattered across broken stage fragments maps onto [start-stop REM feel · brief body shifts · dry mouth on wakelets] inside mixed 6–16 Hz, atonia "partial_failure" — read as mechanism, not dream-symbol shorthand.

Dataset readout: Fragmented REM with micro-arousals in REM (fragmentation). Cortical window 6–16 Hz (mixed). Atonia=partial_failure. Markers drive the text below — not dream-symbol meanings.
- start-stop REM feel
- brief body shifts
- dry mouth on wakelets
Transmitters in this row:
- norepinephrine
- acetylcholine
- orexin
Mechanism stack
- Cortically, this row runs mixed at 6–16 Hz while fragmented REM with micro-arousals, scattered across broken stage fragments plays out in REM sleep.
- Norepinephrine leads the chemistry here (aminergic wake pressure returns toward cortex); acetylcholine, orexin also show up; density for this row is 125.6.
- Dataset row #10018: atonia 60/100, arousal 75/100, coherence 32/100 — the motor brake is only partial, against a jagged, low-coherence backdrop.
- On this fragmentation row the markers stack as "start-stop REM feel" → "dry mouth on wakelets" → "brief body shifts" — each one restarting the signal rather than continuing it.
- The Lab treats "start-stop REM feel" here as fragmentation somatic evidence layered onto imagery for REM sleep — scored as hardware, not metaphor.
If your recall includes "start-stop REM feel" during fragmentation REM sleep, Lab Search weights it as somatic context beside the imagery — mechanism first, not symbolism.
Felt on waking
On waking, the marker named most often is "start-stop REM feel" with "brief body shifts" close behind. Because this row sits at fragmentation in REM sleep, it arrives in disconnected pieces rather than one continuous thread.

This row connects to Cycle timing — how episodes lengthen and shift across the night.
How Lab Search uses this row
The Lab does not look up "start-stop REM feel" in a symbol table — tied here to norepinephrine activity; it uses it to weight the BODY line of your REM reading toward mechanism.

How to read REM/fragmentation: Fragmented REM with micro-arousals
This row is Fragmented REM with micro-arousals in REM (fragmentation). Cortical window 6–16 Hz (mixed). Atonia state: partial_failure. Density 125.6. Chart seed 10018 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.
Gauges on this page: atonia 60, arousal 75, coherence 32. Markers: start-stop REM feel, brief body shifts, dry mouth on wakelets. Transmitters tagged: norepinephrine, acetylcholine, 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 "start-stop REM feel" with "brief body shifts" close behind. Because this row sits at fragmentation in REM sleep, it arrives in disconnected pieces rather than one continuous thread. If your recall includes "start-stop REM feel" during fragmentation REM sleep, Lab Search weights it as somatic context beside the imagery — mechanism first, not symbolism.

How Lab Search should use this row
The Lab does not look up "start-stop REM feel" in a symbol table — tied here to norepinephrine activity; it uses it to weight the BODY line of your REM 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 Fragmented REM with micro-arousals 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.
