The Ghosts of Ayahuasca: Conceptual Limits and Spectral Residues
Anthropology of Consciousness September 25, 2025 Jacob W. Glazier, Sean O’donnell
Ayahuasca, a psychoactive brew used in shamanic rituals, evokes experiences of spirits and mystical entities that challenge materialist views of reality. Its active compound, DMT, is both an endogenous neurotransmitter and an exogenous psychedelic, blurring the boundary between natural and external. Encounters with discarnate beings during ayahuasca journeys defy traditional ontological categories, suggesting these entities are phenomenologically real yet incorporeal. The essay argues that ayahuasca's spectral residues disrupt anthropocentric and biomedical assumptions, leaving traces that haunt these models and invite broader reflections on consciousness, interconnection, death, and metaphysical limits. Listening to these ghosts expands understanding of reality and embraces transformative possibilities.
