Trauma creates a persistent sense of danger in the brain, particularly affecting the amygdala and the periacular gray. This can lead to a shutdown of body awareness, leaving individuals feeling disconnected and often resorting to substances to feel alive. The experience of trauma manifests as a constant, subliminal dread, akin to a dog that never quite feels comfortable in its surroundings. Understanding these effects is crucial for recognizing the struggles faced by those who have experienced trauma.
