Near-death experiences (NDEs) are profound personal encounters associated with death or impending death, characterized by a range of sensations that can include detachment from the body, feelings of peace, life review, and encounters with a light or deceased relatives. While common elements exist, individual interpretations are shaped by cultural, philosophical, and religious beliefs. These experiences typically occur during reversible clinical death, with explanations varying from scientific hypotheses regarding brain function to spiritual beliefs about an afterlife.

Research into NDEs has evolved since the late 19th century, with key figures like Albert Heim, Celia Green, Elisabeth Kübler-Ross, John C. Lilly, and Raymond Moody contributing to the understanding and terminology. Moody, in particular, identified fifteen elements of NDEs, encompassing the experience itself and its aftermath. Later researchers like Kenneth Ring proposed stage-based models. Modern guidelines emphasize distinguishing authentic NDEs, occurring during critical physiological states, from 'mislabeled' experiences that may arise in different contexts, ensuring a clearer focus on death-related phenomena.

A near-death experience (NDE) is a deeply personal event that occurs when someone is close to death or undergoing clinical death. These experiences share common characteristics, though their interpretation is influenced by individual cultural and religious backgrounds. Typical sensations include a feeling of leaving one's body, a sense of profound peace, a review of one's life, and encountering a bright light or deceased loved ones. While most NDEs are reported as positive, some can be distressing. Scientific explanations often point to neurological processes triggered by physiological stress, while spiritual perspectives link them to an afterlife.

The study of near-death phenomena dates back to the late 19th century, with early observations by figures like Albert Heim documenting life reviews during falls. The term 'near-death experience' itself was popularized by psychiatrist Raymond Moody in 1975, building on earlier work by researchers like Celia Green and Elisabeth Kübler-Ross. Moody identified fifteen key elements of NDEs, ranging from out-of-body sensations and tunnel experiences to life reviews and encounters with a 'being of light.' Kenneth Ring later simplified these observations into a five-stage continuum. More recent research aims to distinguish authentic NDEs, tied to critical physiological states, from similar experiences that may occur under different conditions, ensuring the focus remains on phenomena directly related to the brink of death.

Raymond Moody's extensive research identified core components of the NDE, including the sensation of being dead, feelings of peace replacing pain, moving through a tunnel, detaching from the body, meeting deceased individuals, a panoramic life review, and reaching a boundary before returning to life. He also noted post-experience effects like sharing the experience and a changed perspective on death. Kenneth Ring proposed a five-stage model: peace, body separation, entering darkness, seeing the light, and entering another realm. Crucially, the interpretation of these elements is highly personal, often reflecting the experiencer's existing beliefs. For instance, a 'light' might be seen as divine, an angel, or a deceased relative, depending on cultural context.

Recent guidelines highlight the importance of differentiating genuine near-death experiences, which occur during critical physiological states like cardiac arrest, from 'mislabeled' NDEs. These latter experiences might happen under less dire circumstances, such as during general anesthesia or other non-life-threatening events, and may not share the same profound, transformative qualities. Authentic NDEs are characterized by coherence, meaning, purpose, and ineffability, often arising paradoxically during states of reduced brain function. Experiences induced by certain substances or conditions like seizures or dreams tend to display different features, such as distorted body sensations or varied, less coherent imagery, and are not considered authentic NDEs.
