During a traumatic event, however, the brain enters survival mode. The amygdala, which handles emotional processing and threat detection, becomes hyperactive.

Instead of a cohesive story, the memory is encoded as fragmented sensory snapshots.
This lack of integration means the brain fails to signal that the danger has passed. The neurological imprint remains in a raw,
