Exploding-head sensory burst (physiological) in N1 sleep (onset)
Dataset row #10029 frames exploding-head sensory burst (physiological), catching the transition into this stage — glutamate + norepinephrine + acetylcholine against arousal 90/100 and coherence 20/100.

Dataset readout: Exploding-head sensory burst (physiological) in N1 (onset). Cortical window 5–12 Hz (mixed). Atonia=N/A. Markers drive the text below — not dream-symbol meanings.
- loud internal bang percept
- scalp jolt
- startle freeze
Transmitters in this row:
- glutamate
- norepinephrine
- acetylcholine
Mechanism stack
- N1 sleep frames exploding-head sensory burst (physiological), catching the transition into this stage, against a mixed trace of 5–12 Hz.
- Glutamate leads the chemistry here (glutamatergic excitation can outpace local inhibition); norepinephrine, acetylcholine also show up; density for this row is 118.
- Dataset row #10029: atonia 22/100, arousal 90/100, coherence 20/100 — inhibition is weak, leaving room for movement, over an unsettled, choppy backdrop.
- On this onset row the markers stack as "loud internal bang percept" → "scalp jolt" → "startle freeze" — stacking up right before the cycle settles.
- The Lab treats "loud internal bang percept" here as onset somatic evidence layered onto imagery for N1 sleep — read as mechanism, not dream-symbol shorthand.
The Lab treats "loud internal bang percept" as a mechanism marker when it shows up at stage entry in N1 sleep — not something to look up in a dictionary.
Felt on waking
On waking, the marker named most often is "loud internal bang percept" with "scalp jolt" close behind. Because this row sits at onset in N1 sleep, it is easy to mistake for a stray thought rather than a body event.

How Lab Search uses this row
When your recall names "loud internal bang percept" — tied here to glutamate activity, Lab Search reads it as body-side evidence for the BODY line of the matching page rather than as a symbol. It adjusts the mechanism ranking for N1 sleep instead of guessing at what "loud internal bang percept" might "mean".

How to read Exploding-head sensory burst (physiological) in N1 sleep (onset)
This row is Exploding-head sensory burst (physiological) in N1 (onset). Cortical window 5–12 Hz (mixed). Atonia state: N/A. Density 118. Chart seed 10029 is deterministic for this URL — the trace is a model of the row, not a clinical EEG.
Gauges on this page: atonia 22, arousal 90, coherence 20. Markers: loud internal bang percept, scalp jolt, startle freeze. Transmitters tagged: glutamate, norepinephrine, acetylcholine. 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 "loud internal bang percept" with "scalp jolt" close behind. Because this row sits at onset in N1 sleep, it is easy to mistake for a stray thought rather than a body event. The Lab treats "loud internal bang percept" as a mechanism marker when it shows up at stage entry in N1 sleep — not something to look up in a dictionary.

How Lab Search should use this row
When your recall names "loud internal bang percept" — tied here to glutamate activity, Lab Search reads it as body-side evidence for the BODY line of the matching page rather than as a symbol. It adjusts the mechanism ranking for N1 sleep instead of guessing at what "loud internal bang percept" might "mean". Then open Decode if you also have a plot. The plot is optional; the body line is not.
This utility will not treat Exploding-head sensory burst (physiological) 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.
