Meditation-related harm is not fringe. The Varieties of Contemplative Experience study built a taxonomy of meditation-related challenges and framed them as experiences “typically underreported.” An independent assessor in a controlled mindfulness trial found adverse effects in 58% of participants and negative impacts on functioning in 37% — with the lasting effects (6–14%) “associated with signs of dysregulated arousal (hyperarousal and dissociation).” A widely-cited estimate puts an adverse effect lasting more than a month at roughly one in ten people who have meditated, including after a single practice.
And then the strange part. In a recent survey of 121 people with meditation-related difficulties, 61.7% of the meditation-triggered group scored above the clinical cutoff for depersonalization — yet almost none carried a diagnosis, and the same state was described as “more welcome, pleasant, and spiritually meaningful” than the comparison group’s identical phenomenology.
The phenomenology is common. The label is rare. The state is often experienced as good. And the self-report instruments cannot reliably see it (the standard dissociation taxon false-positives at 54% in non-clinical samples).
Why does a failure mode this common stay this invisible? That is the question this post tries to answer — with a measured control-theoretic model of self-regulation.
The short version:
That last point is the useful one. If it is right, the reporting gap will not close with better questionnaires. It closes with relocated measurement — the body, behavior, an external observer — and with the provision the traditions built and modern delivery dropped: a frame before you arrive, community around you, and pace metered, plus a holder chosen in advance who can act when the state cannot act for itself.
(The model is a deterministic ODE from a single case; the mapping to practice is an interpretation, not a measurement. It is offered as one falsifiable hypothesis to the people who measure these things — not as a clinical claim.)
