This paper presents phenomenology of out- of-body experiences (OBEs) occurring spontaneously or pathologically triggered as well as other types of anomalous perceptual experiences such as near- death- experiences (NDEs), temporal lobe irregularities, and ictal autoscopic phenomena (IAP). The paper further presents a brief overview of some of the OBEs studied in both the healthy and pathological populations, as well as anomalous perceptual experiences, with features common to OBEs, in the healthy population, as well as, pathological population. KEY WORDS anomalous perceptual experiences, out-of-body experiences, near- death-experiences, ictal autoscopic phenomena.

Neuroscientists keep telling us that the brain produces consciousness and consciousness does not survive brain death because it ceases when brain activity ceases. Research findings on near-death-experiences during cardiac arrest contradict this widely held conviction. They raise perplexing questions with regard to our current understanding of the relationship between consciousness and brain functions. Reports on veridical perceptions during out-of-body experiences suggest that consciousness may be experienced independently of a functioning brain and that self-consciousness may continue even after the termination of brain activity. Data on studies of near-death-experiences could be an incentive to develop alternative theories of the body-mind relation as seen in contemporary neuroscience.

Mystical and religious experiences are hypothesized to be evoked by transient, electrical microseizures within deep structures of the temporal lobe. Although experiential details are affected by context and reinforcement history, basic themes reflect the inclusion of different amygdaloid-hippocampal structures and adjacent cortices. Whereas the unusual electrical coherence allows access to infantile memories of parents, a source of god expectations, specific stimulation evokes out-of-body experiences, space-time distortions, intense meaningfulness, and dreamy scenes. The species-specific similarities in temporal lobe properties enhance the homogeneity of cross-cultural experiences. They exist along a continuum that ranges from “early morning highs” to recurrent bouts of conversion and dominating religiosity. Predisposing factors include any biochemical or genetic factors that produce temporal lobe lability. A variety of precipitating stimuli provoke these experiences, but personal (life) crises and death bed conditions are optimal. These temporal lobe microseizures can be learned as responses to existential trauma because stimulation is of powerful intrinsic reward regions and reduction of death anxiety occurs. The implications of these transients as potent modifiers of human behavior are considered.

‘Altered states of consciousness’ discusses the states of consciousness during sleep, dreaming, hallucinations, out-of-body experiences, near-death experiences, meditation, and after taking psychoactive drugs. Psychologist Charles Tart defines an altered state of consciousness (ASC) as ‘a qualitative alteration in the overall pattern of mental functioning, such that the experiencer feels his consciousness is radically different from the way it functions ordinarily’. This certainly captures the idea of ASCs, but also creates problems, such as knowing what a ‘normal’ state is. In both mystical experiences and long-term meditation, people describe seeing through the illusions of duality and seeing the world as it truly is.

This chapter outlines how the term “out-of-the-body experience” emerged in spiritualist and parapsychological literature. As is shown, “psychical researchers” such as Frederic W. Myers and William James made a significant contribution. The chapter also deals with the “filter” theory or “transmission” theory, i.e., the idea of the brain as a means for the inhibition of consciousness. This theory, as is shown, has been developed in close interaction with phenomena “near death”—in particular, the “panoramic life review.” The filter theory, discussed in subsequent chapters 2.6. and 2.7, too, is still favored by many recent protagonists of near-death experiences (e.g., Moody). Finally, the chapter turns to the increase of autoscopic out-of-body experiences, discussed as a phenomenon attesting a changing relationship of the disembodied consciousness toward its own body.

This book offers a modern genealogy of “near-death experiences,” outlining the important functions of these experiences in the religious field of Western modernity. Emerging as autobiographical narratives in the legacy of Christian deathbed visions, narratives of near-death experiences were used in Western religious metacultures (Christian, Esoteric, and Spiritualist–Occult) as substantial proof for the survival of death. In its historical part, the study demonstrates how certain features of near-death experiences, for example, the panoramic life review or autoscopic out-of-body-experiences, emerged in Occult and Esoteric circles in the 19th and 20th centuries, experimenting with astral projection, drugs, and “clairvoyant” states. It was only in the 1970s, however, that Raymond Moody, popularizing the generic term “near-death experience” that had been introduced by John C. Lilly, could declare the different features to be elements of a single phenomenon. Other factors that paved the way were discussions on “brain death,” coma, and the increase of hospitalized dying, the crisis of traditional religious institutions in the 1960s and early 1970s, and the claim of individual religious experiences. In its systematic part, the study discusses the religious relevance of these experiences for the experiencers themselves, but also for the growing audience of such testimonies. These functions encompass ontological, epistemic, intersubjective, and moral aspects. Most central is the reassurance that in modernity, religious experience is still possible, and that near-death experiences may initiate a new spiritual orientation in life. In addition, they are held to offer evidence for the transcultural validity of afterlife visions.

SYNOPSISA survey of five group practices in South London identified 60 male patients currently undergoing treatment for epilepsy. Fifty-four agreed to participate in a detailed enquiry into aspects of their sexual activity and behaviour. Anterior pituitary and sex-hormone levels were measured. The epileptic patients were characterized by low levels of sexual activity and interest. Temporal-lobe and non-temporal-lobe epileptics were indistinguishable in these respects, but when the latter group was further subdivided into primary generalized epilepsy and focal non-temporal lobe epilepsy, the focal groups (both temporal lobe and non-temporal lobe) were more impaired. Hormonal analysis confirmed earlier hospital-clinic-based reports. In the epilepsy group, plasma free testosterone and percentage free testosterone values were decreased, sex hormone binding globulin, luteinizing hormone (LH) and follicle stimulating hormone (FSH) were increased compared to values in a normal healthy population. As association between the behavioural and hormonal indices of hyposexuality was shown, particularly for LH, but this was less apparent than in previous work.

The aim of this paper is to describe some ostensibly odd, Non-Ordinary-Mental Expressions (NOMEs), that have been considered implausible, illusory or hallucinatory phenomena, possible symptoms of disorders of the neurological or psychological functioning. They include a large variety of phenomena, encompassing hearing voices, seeing presences, communication with non-incarnated entities (including channeling), transpersonal experiences, out-of-body experiences, near-death-experiences, previous life memories, presentiments and precognitions, seeing at distance, mind interactions at a distance, mind-matter interactions at distance. We think that individuals experiencing NOMEs should not feel like they were outsiders or diseased; they should feel free to talk about their uncommon experiences and be listen to with an open, not-judging mind, respecting the patients’ experience and narration. In fact, NOMEs are non-pathological phenomena laying in a still misunderstood grey area between mental health and psychological or psychiatric disorders, while some of them suggest intriguing properties of human consciousness. Their ostensible incompatibility with some axioms and theories of consciousness, shows the inescapable epistemological implications of their proper investigation and understanding.
