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

Summary

Near-death experiences (NDEs) and psychedelic drug experiences (YDEs) provide unique insights beyond ordinary perception and can alleviate death-related anxiety. Recent findings indicate that multi-person virtual reality experiences (VREs) designed with a numadelic aesthetic, representing bodies as light energy, yield psychometric results similar to YDEs. This article explores the theoretical underpinnings of the numadelic aesthetic and proposes how it can model NDEs, potentially offering new ways to address death anxiety.

Abstract

Near-death experiences (NDEs) and psychedelic drug experiences (YDEs) enable access to dimensions of non-ordinary sensation, perception, and insight beyond typical day-to-day phenomenology. Both are associated with a dissolution of conventional spatio-temporal conceptual distinctions, and a corresponding sense of connectedness and unity. Moreover, NDEs and YDEs have shown a remarkable ability to reduce the anxiety that people associate with death. In two recent papers, we showed that multi-person virtual reality experiences (VREs) designed within the ‘numadelic’ aesthetic (where bodies are represented as light energy rather than material objects) can elicit psychometric results comparable to YDEs. It nevertheless remains an open question why numadelic aesthetics achieve the observed results, especially given that the vast majority of VREs represent bodies as typically perceived in the ‘real-world’. This article describes the origins of the numadelic aesthetic from subjective accounts of NDE phenomenology, and attempts to unravel mechanistic aspects of the numadelic aesthetic by embedding it within a more general theoretical framework. Specifically, we elaborate a 2-axis schematic grounded in predictive coding models of cognition and matter-energy ideas from physics. One axis tracks ‘structural specificity’, and the other tracks ‘symbolic rigidity’. The majority of VREs, which emphasize photorealistic fidelity to content derived from ‘day-to-day’ phenomenology, are characterized by high structural specificity and high symbolic rigidity. Such approaches collapse imaginative potential into a limited low-entropy space of ‘exogenous’ possibility, unlike the high-entropy brain states associated with YDEs. In contrast, aesthetic domains characterized by low structural specificity and low symbolic rigidity are less concerned with fidelity to phenomenological priors, offering an expansive, ‘uncollapsed’ high-entropy possibility space into which participants can project meaning and corresponding endogenous insights can arise (e.g., as occurs in NDEs and YDEs). Situated within this theoretical framing, the numadelic aesthetic emerges as a practical example of an un-collapsed approach to representation, helping to explain the experimental observations within previous papers. Moreover, the theoretical framing suggests various experimental tests, and lays the groundwork for applying numadelic aesthetics to model NDEs, to help address the anxiety often associated with death.
