Alpha intrusion into NREM · alpha 8–12 Hz · N2
Alpha intrusion into NREM, cut into pieces by fragmentation bursts maps onto [unrefreshing stillness · muscle tension pockets · light sleep feel] inside alpha 8–12 Hz, atonia "N/A" — a mechanism read, not a symbol lookup.

Dataset readout: Alpha intrusion into NREM in N2 (fragmentation). Cortical window 8–12 Hz (alpha). Atonia=N/A. Markers drive the text below — not dream-symbol meanings.
- unrefreshing stillness
- muscle tension pockets
- light sleep feel
Transmitters in this row:
- norepinephrine
- histamine
- GABA
Mechanism stack
- Alpha intrusion into NREM, cut into pieces by fragmentation bursts sits inside N2 sleep, with cortical activity running alpha at 8–12 Hz.
- Norepinephrine leads the chemistry here (aminergic wake pressure returns toward cortex); histamine, GABA also show up; density for this row is 104.
- Dataset row #10019: atonia 38/100, arousal 58/100, coherence 45/100 — the motor brake is only partial, over a middling, mixed backdrop.
- On this fragmentation row the markers stack as "unrefreshing stillness" → "muscle tension pockets" → "light sleep feel" — each fragment resetting rather than building on the last.
- The BODY line on this page leans on "unrefreshing stillness" for this fragmentation/N2 row — treated as physiology here, not folklore.
If your recall includes "unrefreshing stillness" during fragmentation N2 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 "unrefreshing stillness" with "muscle tension pockets" close behind. Because this row sits at fragmentation in N2 sleep, it shows up as a handful of unrelated snapshots instead of a story.

How Lab Search uses this row
Naming "unrefreshing stillness" — tied here to norepinephrine activity shifts the Lab's N2-sleep reading toward physiology — the BODY line moves, the SIGNAL line does not chase a symbolic guess.

How to read Alpha intrusion into NREM · alpha 8–12 Hz · N2
This row is Alpha intrusion into NREM in N2 (fragmentation). Cortical window 8–12 Hz (alpha). Atonia state: N/A. Density 104. Chart seed 10019 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.
Gauges on this page: atonia 38, arousal 58, coherence 45. Markers: unrefreshing stillness, muscle tension pockets, light sleep feel. Transmitters tagged: norepinephrine, histamine, 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
Naming "unrefreshing stillness" — tied here to norepinephrine activity shifts the Lab's N2-sleep reading toward physiology — the BODY line moves, the SIGNAL line does not chase a symbolic guess. Then open Decode if you also have a plot. The plot is optional; the body line is not.
This utility will not treat Alpha intrusion into NREM 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.
