Full abstract: Since 1975 when Raymond Moody published his influential work on near-death experiences (NDEs), controversy has existed among researchers regarding the nature and source of these phenomena. Some researchers have attributed various NDE features to physiological changes in the human body; one such feature that many experiencers have reported is rapid movement through a tunnel toward a light, which materialists have reduced to anoxic narrowing of the visual field. Although experiencers themselves and some researchers have disagreed with materialist, reductionist explanations, limited evidence has existed to contribute to a resolution of the dispute. In this article, we present a case study of an adult male who experienced both gravity induced loss of consciousness (G-LOC) as a Korean War aviation cadet, including narrowing of his visual field to a point of light and also two subsequent transpersonal experiences -- a near-death experience (NDE) and an after-death communication (ADC) -- that both included a tunnel-and-light feature. His Near-Death Experience Scale scores for each experience and his comparison of the qualia of these experiences provide unique evidence in the debate about the nature and likely origins of such experiences. These data place more weight on the argument that the tunnel and light in transpersonal experiences cannot reasonably be attributed to loss of oxygen in the brain.
