Isness: Using Multi-Person VR to Design Peak Mystical Type Experiences Comparable to Psychedelics

April 21, 2020 David R. Glowacki, Mark D. Wonnacott, Rachel Freire et al. 53 citations

A virtual reality (VR) experience called 'Isness', designed using concepts from psychedelic research, can induce mystical-type experiences (MTEs) comparable to those from high doses of psilocybin or LSD. In a study of 57 participants, responses to a standard psychedelic experience questionnaire showed MTEs similar to those reported in double-blind clinical trials. The authors suggest that both psychedelic drugs and VR belong to a broader spectrum of psychedelic technologies. Within a supportive setting, VR can create conditions for MTEs that participants find insightful and meaningful.

Group VR experiences can produce ego attenuation and connectedness comparable to psychedelics

Scientific Reports May 30, 2022 David R. Glowacki, Rhoslyn Roebuck Williams, Mark Wonnacott et al. 44 citations

A virtual reality framework called Isness-distributed (Isness-D) enables groups of people in a shared virtual space to experience their bodies as luminous energetic essences with diffuse boundaries, allowing moments of 'energetic coalescence' where bodies fluidly merge and participants include multiple others within their self-representation. In a citizen science study with 58 participants across an international network of Isness-D nodes, scores on four self-report scales (inclusion of community in self, ego-dissolution inventory, communitas scale, and MEQ30 mystical experience questionnaire) were statistically indistinguishable from those reported in recent psychedelic drug studies. This demonstrates that distributed VR can design intersubjective self-transcendent experiences where people dissolve their sense of self in connection to others.

VR models of death and psychedelics: an aesthetic paradigm for design beyond day-to-day phenomenology

Frontiers in Virtual Reality January 29, 2024 David R. Glowacki 11 citations

Near-death experiences (NDEs) and psychedelic drug experiences (YDEs) dissolve ordinary spatio-temporal distinctions and foster a sense of unity, while also reducing death-related anxiety. Virtual reality experiences (VREs) designed with a 'numadelic' aesthetic—representing bodies as light energy rather than material objects—can produce psychometric results comparable to YDEs. This article traces the numadelic aesthetic's origins to NDE phenomenology and explains its effects through a theoretical framework grounded in predictive coding and physics. A two-axis schematic distinguishes typical VREs (high structural specificity and symbolic rigidity, which limit imaginative possibility) from numadelic aesthetics (low on both axes, which open a high-entropy space for endogenous insight). This framework accounts for prior experimental findings and suggests tests for modeling NDEs to address death anxiety.

Inducing selflessness through a numadelic virtual reality experience: a preliminary study

Virtual Reality December 21, 2025 Joana Vidal, Catherine I. Andreu, Maja Wrzesien et al.

A single multi-person virtual reality experience can induce a state of selflessness—where the sense of self as the immediate subject of experience fades—and enhance interpersonal connectedness. It also increases low-arousal positive affect and warmth, and generates mystical and peak experiences in a notable subset of participants. The experience is widely accepted, with few adverse effects reported. This offers a cost-effective, non-pharmacological alternative to meditation and psychedelics for cultivating selflessness.

Lucid dreaming of a prior virtual-reality experience with ego-transcendent qualities: A proof-of-concept study

June 20, 2025 Daniel Morris, Blaise Elliott, Susana G. Torres‐platas et al. preprint

Combining virtual reality (VR) with lucid dreaming—where a person knows they are dreaming—can create more profound experiences than VR alone. In this study, four frequent lucid dreamers experienced a VR simulation called Ripple, which previously reduced self-other boundaries and enhanced feelings of interconnectedness. Afterward, during REM sleep, sounds from Ripple were played quietly. Three participants had lucid dreams about Ripple, and all four reported dreams containing elements of the VR experience. Lucid dreams were validated in real time via physiological signals. The findings confirm that people can have lucid dreams that recapitulate prior VR experiences, suggesting a synergistic benefit for immersive exploration.

Dissolving yourself in connection to others: shared experiences of ego attenuation and connectedness during group VR experiences can be comparable to psychedelics

arXiv Preprint Archive May 17, 2021 David R. Glowacki, Rhoslyn Roebuck Williams, Olivia M. Maynard et al.

A distributed virtual reality framework called Isness-D, in which groups of people co-inhabit a shared space as luminous, diffuse bodies, can produce self-transcendent experiences statistically indistinguishable from those induced by psychedelic drugs. In a citizen-science experiment with 58 participants across an international network, scores on four standard scales—ego-dissolution, inclusion of community in self, communitas, and mystical experience—were comparable to published psychedelic studies. The findings demonstrate that distributed multi-person VR can reliably blur self-other boundaries and create intersubjective experiences of merging with others.

Virtual reality can create profound experiences of connection and ego dissolution comparable to psychedelic drugs, but without substances. In groundbreaking human-computer interaction (cs.HC) research, participants experienced their bodies as luminous energy forms in shared virtual spaces, allowing them to merge and connect with others in unprecedented ways. Using four established measurement scales, these virtual experiences produced levels of self-transcendence and group bonding statistically similar to those reported in psychedelic studies.

Isness: Using Multi-Person VR to Design Peak Mystical-Type Experiences Comparable to Psychedelics

arXiv Preprint Archive February 3, 2020 David R. Glowacki, Mark D. Wonnacott, Rachel Freire et al.

Virtual reality can induce profound mystical experiences similar to those triggered by psychedelic substances, without the need for drugs. A groundbreaking human-computer interaction (cs.HC) experiment showed that carefully designed VR environments can create transformative group experiences where participants perceive themselves as pure energy, fostering deep feelings of connection and transcendence. Data from 57 participants revealed emotional responses matching those reported in clinical studies of psilocybin and LSD.

A virtual reality journey called 'Isness' can induce mystical-type experiences (MTEs) comparable to those from high doses of psilocybin or LSD. In a study of 57 participants, responses to a standard psychedelic experience questionnaire showed MTE levels similar to those in double-blind clinical trials. The authors argue that both psychedelic drugs and virtual reality belong to a broader spectrum of psychedelic technologies. Within a supportive setting, VR phenomenology can create conditions for MTEs that participants find insightful and meaningful.
