Near-death experiences, often abbreviated as NDEs, are reports shared by some individuals who have come close to death or experienced extreme physiological crisis, such as cardiac arrest, severe trauma, or oxygen deprivation. In many cases, these events occur in medical settings where the body is under intense stress and vital functions are temporarily disrupted. People who describe NDEs frequently report a range of similar sensations: a feeling of separation from the physical body, heightened clarity of thought, and the perception of entering a different kind of environment that feels more real than ordinary waking life.

These accounts often include visual impressions such as bright light, peaceful landscapes, tunnels, or nature scenes, along with emotional experiences dominated by calmness, absence of fear, and a strong sense of acceptance. While the details vary widely between individuals and cultural backgrounds, the emotional consistency—especially feelings of peace and detachment from pain—is one of the most commonly reported features. In Robert’s account, the experience began during a critical medical emergency in which his body was failing and doctors were urgently working to stabilize him. From a physiological perspective, situations like cardiac arrest can cause a rapid drop in oxygen supply to the brain, along with disruptions in normal electrical activity.
