Science aims to challenge dogmas, but undemonstrated scientific axioms can themselves become dogmatic when they lead to the rejection of facts that contradict them. Psychobiological explanations of near-death experiences (NDEs) often claim these are mere brain dysfunctions, yet they neglect facts incompatible with a physicalist stance. The transcendent features of NDEs demand a neutral position that distinguishes facts from speculation. Most current psychobiological interpretations remain unproven, and the delirium from brain disorders or drugs differs phenomenologically from NDEs. Facts cannot be dismissed a priori as paranormal, even if implausible; doing so risks turning knowledge into dogma and the scientific paradigm into theology.

Near-death experiences (NDEs) are deep, universal altered states of consciousness with clear phenomenology and incidence, whose features challenge the dominant mechanist-reductionist view of mind as a byproduct of brain circuitry. This paradigm originated from Descartes' separation of mind and matter and the historical conflict between science and the Inquisition, which removed subjective mental properties from scientific inquiry. Twentieth-century physics moved beyond this classical paradigm, renewing scientific interest in mind. Modern NDE research has reopened debate on the mind-brain relationship and consciousness. The authors argue it is time to reappraise scientific interpretations of NDEs, their relationship with other altered states, and the concept of altered state itself, which appears ill-founded, suggesting a need for revision of conventional approaches to subjective phenomena and reflection on links between non-ordinary mental expressions.

Hypnosis and meditation share common features including induction through focused attention and the ability to intentionally control biological and mental processes, but they differ in scope: hypnosis is used pragmatically for specific therapeutic goals, while Eastern meditation pursues broader philosophical aims of liberation from suffering and illusion.

Out-of-body experiences (OBEs) induced through hypnosis provide a controlled way to study the phenomenon. In 15 highly hypnotizable people, OBEs were evoked either as an imaginative task while resting or under hypnosis. Brain activity was recorded with EEG, and participants completed a questionnaire about their experience. The hypnotic OBEs produced stronger feelings of altered state, positive affect, and focused attention, along with decreased beta and gamma brainwave power in the right parieto-temporal region. These findings suggest that hypnotically induced OBEs can serve as a useful experimental model for spontaneous out-of-body experiences.

Five individuals with unusual hypnotic ability, free of psychiatric disorders, spontaneously experienced multiple identities during hypnosis, which they later did not recall due to post-hypnotic amnesia. Brain scans showed reduced connectivity in the Default Mode Network, particularly between the posterior cingulate cortex and medial prefrontal cortex. Comparing these findings with fMRI data from Dissociative Identity Disorder patients suggests a continuum between normal mental functioning, where multiple identities can coexist unconsciously, and pathological dissociation. The authors argue that a sharp boundary between normal and pathological experiences may be artificial, and that non-ordinary mental expressions like these should be understood rather than treated.

Growing scientific interest in spirituality and promising findings on psychedelic-induced spiritual experiences for treating psychiatric disorders are paralleled by risks. Indiscriminate use of psychedelics to induce spiritual experiences may foster psychospiritual pathology, notably spiritual bypassing. This risk arises because psychedelics can trigger transcendental phenomenology, the dominant mechanistic-reductionist paradigm inadequately addresses spirituality, and New Age beliefs promote psychedelics as growth tools. Given the frequency of transcendental phenomenology in psychedelic experiences, psychospiritual assessment and support are needed. Incorporating wisdom from Eastern and Western philosophical and spiritual traditions, from a secular, transcultural perspective, could guide informed practices in psychedelic research and therapy.

Out-of-body experiences (OBEs) induced through hypnosis (H-OBEs) produce stronger phenomenological changes than those induced through imagination alone. In 15 highly hypnotizable participants, H-OBEs led to significantly higher scores on the Altered State, Positive Affect, Altered Experience, and Attention subdimensions of the Phenomenology of Consciousness Inventory, alongside a decrease in beta and gamma band power in right parieto-temporal brain regions. These findings suggest that hypnotically induced OBEs may serve as a useful model for studying genuine OBEs, involving altered multisensory integration in right parieto-temporal areas.
