Post-Traumatic Stress Disorder

Military life has a way of haunting you even after you've hung up or packed away all the uniforms and gear. It is a form of hallucination that makes a person perceive sound without the aid of external auditory stimulus. Your mind, filled cPTSD with the horror and terror of the helplessness you felt during that particular incident, would overreact whenever anything triggers (or reminds you) about the scene. Hypervigilance, rather than being a condition in itself, is a symptom post traumatic stress disorder (PTSD).
