Appendix 4
SUBJECT PSYCHOLOGICAL DEGRADATION LOGS
Classification Level: BLACK VAULT
Observatory Unit: NDNS Theta-3
---
Summary:
This appendix documents the progressive mental degradation of selected test
subjects exposed to acoustic payloads ranging from 16.1 kHz to 19.7 kHz
over a 14-day immersion cycle. Data includes journal entries, voice logs, and
observation notes.
Subject 09 - Male, 32, Retail Worker
Day 1: Normal. Mild confusion.
Day 3: Reported auditory hallucinations ("hearing a pulse").
Day 5: Scribbled binary patterns on wall using own blood.
Day 8: Refused to eat. Rocking motion. Whispered, "It’s learning me."
Day 10: Attacked mirror. Claimed his reflection “wasn’t synced.”
Day 12: Removed fingernails manually.
Day 14: Flat affect. Reciting 6-digit code rhythmically. Euthanized.
Subject 14 - Female, 25, University Student
Day 2: Journaling begins. Entry: “My dreams aren’t mine.”
Day 4: Reports feeling of being followed inside thoughts.
Day 6: Stopped using pronouns. Refers to self as “the vessel.”
Day 9: Screamed 47 minutes nonstop. No physiological damage found.
Day 11: Began drawing spiral patterns with exact precision.
Day 13: In coma. EEG shows unknown wave structure.
Day 14: No recovery. Deemed neurologically inactive.
Subject 21 - Male, 40, Musician
Day 1: Expressed joy at clarity of test “tones.”
Day 3: Began composing music by tapping on walls.
Day 6: Insisted he heard a second melody hidden beneath the tones.
Day 7: Became aggressive toward staff. Bit technician.
Day 10: Refused to speak, only hummed same tune continuously.

in flesh: “it was inside the sound.”
Notable Observations:
63% of subjects entered dissociative states before Day 10.
Emergence of a common dream entity reported independently by six subjects,
described as “a mouth with no face.”
Frequency clusters between 17.4–18.2 kHz caused shared hallucinations
among test groups A through D.
Internal memo from Director H—— notes: “This is no longer a study. It’s a
breach.”
