Post-Traumatic Stress Disorder (PTSD) is a mental health condition that can develop after someone experiences or witnesses a very stressful, frightening, or life-threatening event. This can happen after accidents, abuse, natural disasters, or war. For those with PTSD, memories of the event do not fade. It feels like the brain keeps returning to that moment, as if the danger never ended. https://www.google.com/url?sa=i&url=https%3A%2F%2Fwww.academia.edu%2F14545805%2FThe_weaker

This article explores the NEPTUNE model, a neuroscience framework that explains near-death experiences (NDEs). Instead of mystical visions, NDEs may emerge from brain crisis responses: oxygen loss, hyperactive neural circuits, and a powerful surge of neurotransmitters. Combined with evolutionary defense strategies and psychological interpretation, these processes create the vivid, life-changing experiences survivors often describe as “more real than real life.”
