Surprise and puzzlement expressed in near-death experience (NDE) accounts may indicate genuine discovery of novel features of reality, not mere subjective invention. The article argues that surprise typically arises during the cognition-reality interplay that enables learning. If some NDE surprises represent discoveries in a nonsubjective sense, then that cognition-reality interplay can persist near death, suggesting that self and reality include a nonmaterial realm.

The Life Changes Inventory-Revised is a standardized scale that captures changes in attitudes and values often reported by people who have had near-death experiences. The scale builds on earlier versions tested across diverse samples and incorporates insights from qualitative research on how such experiences transform perspectives on life, death, and relationships. The inventory provides a reliable tool for measuring these shifts systematically.

Keith Augustine's critique of a transcendental interpretation of near-death experiences (NDEs) identifies weaknesses in research methodology, limited data, and gaps in arguments. He cites psychophysiological and cultural correlates favoring a hallucinatory view. However, his analysis relies on idiosyncratic definitions of psychological concepts, assumes unidirectional causality from bivariate correlations, and underestimates empirical predictions of the separation hypothesis. Although evidence for the transcendental hypothesis is not compelling, it accounts for NDE phenomenology better than the materialist model.

Some researchers have proposed that the psychedelic drug DMT, which the body naturally produces in small amounts, might be released in larger quantities during extreme physical stress and cause near-death experiences (NDEs). This paper examines whether DMT could play a causal role in producing NDEs. After reviewing basic information about NDEs, classifying theories of NDEs, and discussing DMT's chemical and psychological effects, the author compares the phenomenology of DMT experiences and NDEs. The conclusion is that the two types of experiences lack sufficient similarity to justify a causal role for DMT in NDEs.

A critique of Keith Augustine's argument against veridical perception in near-death experiences shows that his claims rely on unsubstantiated speculation from popular media rather than on supportive data or peer-reviewed literature. Addressing the issues he raises could improve the methodology of near-death research and strengthen the evidential database for such perceptions.

A letter to the editor responds to Augustine's article questioning whether paranormal perception occurs in near-death experiences. The author challenges the arguments presented in Augustine's work, offering a counterpoint to the skeptical view of paranormal elements in NDEs. The response engages with the philosophical and empirical debate surrounding the validity of paranormal perception during near-death states, suggesting that the evidence may support such phenomena more than Augustine allows.

Ketamine can produce experiences resembling near-death experiences (NDEs), but the nature of these experiences differs depending on the context—recreational use versus use in an operating room. Both ketamine and ibogaine, a substance used in Central African religious rituals to induce NDEs, are noncompetitive antagonists of the NMDA receptor. Ibogaine also elicits different experiences based on whether it is used in a hallucinatory context or in initiatic rituals that induce a superficial coma. These observations raise the question of whether the chemically-induced NDE-like experience stems from the specific substance or from the genuine comatose state itself.
