In psychedelic research and therapy circles, mystical experiences—unity, bliss, cosmic oneness—are often celebrated as the pinnacle. But my recent analysis of real DMT brain data tells a more nuanced story.

Neural volatility predicts bodily detachment and out-of-body experiences far more strongly than any transcendent or blissful states.

This suggests "ego death" may not be a single phenomenon. Instead, it could split into separable dimensions: somatic (body-model disruption) vs. noetic/transcendent (mystical unity).

Study Overview

I re-analysed publicly available EEG data from 34 participants who inhaled N,N-DMT in naturalistic settings (Timmermann et al., Imperial College dataset). Using the Consciousness Gradient Index (CGI = √(integration × complexity)), I focused on dynamic changes—how rapidly and widely the brain's state shifted over 30-second windows—rather than static averages.
These dynamics were correlated with post-session 5D-ASC subscale reports (validated phenomenological tool).

Key Findings

• Static brain metrics (mean integration, complexity, CGI) showed near-zero correlations with phenomenal intensity.

• Dynamic volatility (magnitude of state transitions) strongly predicted bodily ego dissolution:

○ Out-of-body experiences: r = 0.48

○ Disembodiment: r = 0.42

○ Significant across related subscales (bootstrap CIs exclude zero)

• Mystical subscales were essentially flat:

○ Blissful state: r = 0.06

○ Spiritual experience / oceanic unity: not significant (CIs include zero)

Striking bidirectional effect — Both increases and decreases in CGI predicted bodily ego dissolution equally (magnitude mattered, not direction). This aligns with the entropic brain hypothesis: psychedelics relax constraints, expanding explorable state space—but that exploration appears to destabilize the body schema (interoceptive/proprioceptive self-model) more than it generates transcendent unity.

Implications

• For psychedelic-assisted therapy: If ego dissolution correlates with outcomes (e.g., depression relief), targeting volatility (dose, onset speed, setting) could amplify somatic aspects. Mystical/transcendent benefits might rely more on set/intention, music, integration, or post-acute meaning-making.

• Challenges assumptions that ego dissolution automatically unlocks mysticism—separate mechanisms may be at play.

• Highlights need for dimensional specificity in consciousness models (bodily vs. noetic).

Open Questions for the Field

• Why is the body-self model so fragile to neural transitions, while bliss/unity resists? Predictive processing fragility?

• What neural signatures (sustained states? specific bands/networks?) better predict mystical experience?

• Does this pattern hold for slower psychedelics (psilocybin, LSD)?

• Replication interest? Happy to discuss datasets or methods.
