The author reports two cases in which depersonalization occurred during the waking consciousness of individuals who had engaged in meditative techniques designed to alter consciousness. Psychiatrists should be aware of this phenomenon, as the number organizations in the "consciousness movement" is increasing, and should ask people manifesting depersonalization about any involvement in...

In their manual based upon The Tibetan Book of the Dead , Richard Alpert, Ralph Metzner and Timothy Leary discuss the signs of the ‘Third Bardo’ existence in a psychedelic experience in the vocabulary of Ken Kesey's fiction: Where Tibetans saw demons and beasts of prey, a Westerner may see impersonal machinery grinding, or depersonalizing and controlling devices of different futuristic...

The view that depersonalization experiences can “be regarded as occupying a position somewhere between the delusional and the non-delusional” was first suggested by Ackner (1954) who gave as an example the depressive's experience of malaise. If this is accepted into the normal framework of experience it will be attributed to illness or fatigue. If it is accepted and organized into a delusional...

Anomalous subjective recall refers to autobiographical memories whose factual content can be retrieved but are not experienced as one’s own, instead feeling alien. It is thought to reflect disrupted temporal self-continuity during depersonalization; however, its neural basis remains poorly understood. Because task-based measures may be less suitable for capturing trait-like alterations in...

The study examined whether immersive virtual reality (VR) can non-pharmacologically induce psychedelic-like altered states and what predicts their intensity. Fifty-seven adults who had used classic psychedelic within the previous six months completed neutraland psychedelic VR conditions in randomized order. Relative to neutral VR, psychedelic VR elicited higher mystical-type experience...

This paper proposes a qualitative study exploring anomalous self and world-experiences in individuals with high levels of depersonalization traits. Depersonalization (DP) is a condition characterized by distressing feelings of being a detached, neutral and disembodied onlooker of one’s mental and bodily processes or even of reality itself (‘derealization’). Feelings of depersonalization are...

Depersonalization is a common and distressing experience characterized by a feeling of estrangement from one’s self, body and the world. In order to examine the relationship between depersonalization and selfhood we conducted an experimental study comparing processing of three types of self-related information between non-clinical groups of people experiencing high and low levels of...

The sense of agency, i.e. the subjective feeling of voluntarily controlling one’s bodily actions is profoundly altered in Depersonalisation (DP henceforth), a condition that makes people feel detached from one’s self and body. The intentional binding (IB henceforth) effect has been proposed as an influential implicit measure of the sense of agency. IB refers to the phenomenon of perceived...

Cognitive feelings, such as the feeling of knowing, familiarity, presence, reality, confidence, agency, and body ownership, are subjective experiences arising from cognitive processes, playing crucial roles in perception, memory, and decision-making. Despite extensive research across philosophy, psychology, and neuroscience, they have been studied in fragmented ways, lacking a unified...

Anomalous self-experiences (ASEs) and basic self-disturbance have been proposed as core, and specific, markers of schizophrenia-spectrum disorders (SSD), operationalized through instruments such as the Examination of Anomalous Self-Experience (EASE). Many of the phenomena grouped under the ASE construct, derealization, depersonalization, altered embodiment, unstable self–world boundaries,...
