RECOVERY SUMMARY Clinical discussion of mass psychogenic illness was extracted with one biometric cluster attached. Three unrelated sleep labs logged the same REM-onset interval, 11.4 minutes, across 27 subjects.
EXTRACTED DATA Source context concerns Havana Syndrome, social contagion, and psychogenic symptom formation in diplomatic and occupational groups. Extracted comparison set: 3 polysomnography labs, 3 countries, 27 adult subjects, recording window 2026-03-18 to 2026-03-24.
Lab A reported REM latency median 91.2 min. Lab B: 91.2 min. Lab C: 91.2 min. Historical inter-lab variance for matched sleep studies, 2016-2025 baseline: 3.8-6.1%. Device models differed in 3/3 sites. Calibration logs show no synchronized maintenance event.
A secondary field matched exactly across all files: interval from stage N2 onset to first phasic REM marker, 11.4 min in 27/27 records. File timestamps differed by 6-19 hours. Subject contact between cohorts: not established.
Cluster classified. Etiology: not determined.
INTEGRITY NOTES Integrity check: passed. Data extraction within standard parameters. One metadata value is at the edge of acceptable range. Flagged.
