Informe de Observación Neurofenomenológica sobre Estados Alterados de Conciencia Inducidos por Psilocibina

Summary

The analysis explores the subjective experience of a psilocybin session, emphasizing changes in bodily awareness, spatial perception, visual imagery, and self-representation. It documents these experiences through notes and reconstruction, linking them to current neuroscientific models like ego dissolution and altered sensory integration. The aim is to describe the structures of experience under psilocybin without making metaphysical claims about the phenomena.

Abstract

This report presents a detailed phenomenological analysis of a self-observed psilocybin experience conducted under controlled conditions and documented through contemporaneous notes and post-session reconstruction. The study focuses on the structure of subjective experience rather than on pharmacological outcomes alone. Particular attention is given to alterations in bodily awareness, spatial perception, visual imagery, attentional dynamics, autonomous verbal phenomena, experiences of presence, transformations of self-representation, and processes of autobiographical reintegration occurring during and after the altered state. The analysis is informed by phenomenology, neurophenomenology, cognitive science, consciousness studies, and contemporary psychedelic research. Experiential observations are discussed in relation to current neuroscientific models including ego dissolution, predictive processing, altered sensory integration, and large-scale network reorganization associated with psychedelic states. The document combines raw experiential reports, analytical commentary, methodological reflections, and an interdisciplinary bibliographic framework drawing from psychology, neuroscience, philosophy, anthropology, and contemplative traditions. The objective is not to establish metaphysical claims regarding the ontological status of the reported phenomena, but rather to describe and examine the experiential structures that emerge under psilocybin and to explore possible interpretative frameworks through which such experiences may be understood.
