Somatic sleep metric utilities

Why somatic gets its own hub

Indexed dataset: 50 high-density utilities. Full DB held offline from index until promoted. This hub is not a blog about “somatic dreams.” It is the index of 50 high-density metric utilities currently allowed to crawl. Each card is a different symptom × somatic × context triple. Same phase, different hardware. Mixing N1/N2/N3/REM into one omen paragraph is how thin pages get born; this URL refuses that mix.

Contexts present in the live somatic index: awakening, onset, fragmentation, mid-cycle. Symptom families: Hypnopompic somatic surge, Pre-REM atonia ramp, Fragmented REM with micro-arousals, Distal REM muscle twitches, Sleep paralysis at REM–wake border, Partial REM atonia failure, Hypnopompic residual immobility, Exploding-head sensory burst (physiological), Periodic limb movements in sleep, Confusional arousal motor residue (N3 exit), Sleep-onset breathing pause (physiological), Hypnic myoclonus (sleep start), Tachycardia in hypnagogia, Sleep-related bruxism (jaw clenching), Alpha intrusion into NREM, Sleep-related bruxism, Microsleep nod into N1, Exploding-head sensory burst, Hypnagogic falling-elevator, Hypnagogic limb-float percept, REM thermoregulatory blunting, Phasic REM eye-twitch burst, REM sawtooth-wave window, REM-linked genital engorgement (physiological), Morning cortisol-linked motor readiness. If two links look similar, read the context suffix — onset is not awakening; fragmentation is not mid-cycle. Cortical language for this stage stays inside somatic physiology, not a personality metaphor.

How to work a night that belongs on this hub: 1) write the first twenty seconds of residue (heat, weight, mute, twitch, jaw, breath). 2) pick the somatic card whose title names that residue. 3) read that row’s gauges and markers — numbers are URL-specific. 4) carry the row into Lab Search; do not paste a symbol. 5) if the night was mostly plot, use Dream Meaning; if it was mostly body, stay in /somatic.

somatic is a sleep-architecture label, not a type of person. N1 is a theta gate into sleep, N2 a sigma/spindle window, N3 a delta well, REM a dreaming state with spinal atonia. This page only lists somatic. Neighbor hubs: N1, N2, N3, REM.

What this hub will not do: diagnose apnea, REM sleep behavior disorder, or psychiatric disease. Persistent dream enactment, choking, or daytime collapse needs a clinician. What it will do: keep somatic metrics honest so Decode is not guessing from a plot summary. Methodology lives on About; Lab Notes by Vigen sit at /notes.
