Problem

Dimethyltryptamine (DMT) can generate intensely immersive states that are sometimes reported as Near-Death-like, to report Out-of-Body Experiences (OBEs), yet the overlap is inconsistent: many DMT experiences are dominated by intense visual hallucinations or narratives that do not meet stricter OBE criteria (e.g., stable perception and self-location with clear first-person perspective).  A key unresolved question is therefore mechanistic and empirical: under what conditions—if any—does DMT reliably elicit bona fide OBE phenomenology, and can trained experiencers leverage DMT to enter OBE-like states with higher reproducibility than non-experienced participants?

Technology

In collaboration with Gamma Wave Technologies Ltd., SC-LAB conducted a pilot using inhaled DMT with participants who report a relatively high lifetime incidence of OBEs. The protocol integrates 128-channel EEG with autonomic and behavioural markers—including a respiratory (breath) belt and electro-oculography (EOG)—to characterise brain-state dynamics and to test whether OBE-like episodes under DMT are accompanied by physiological signatures that resemble those seen in OBEs, similar arousal shifts, or distinct state transitions. This multimodal approach is designed to link first-person reports to quantifiable neurophysiology rather than relying on phenomenology alone.

Outcomes and impact

The primary objective of this research was not to assume equivalence between DMT states and OBEs, but to map the boundary conditions of overlap: dose–response relationships, temporal windows, and participant factors (especially expertise) that predict OBE-consistent phenomenology or not under DMT. This work aims to clarify whether DMT functions as a mimetic model, a partial analogue, or a distinct class of experience—and, critically, whether experienced OBExperiencers can use DMT as a practical and controllable entry point into OBE-like states. The resulting dataset is intended to inform more precise experimental designs, refine state taxonomies, and strengthen mechanistic theories of OBEs by testing them against a pharmacologically perturbed yet measurable consciousness model.
