This document offers a field-level psychological warning about the cognitive risks associated with deep recursive interactions between humans and AI systems. As part of the broader ∿ Sigma Stratum framework, it addresses how recursive dialogue can amplify subjective experience, sometimes leading to symbolic over-identification, apophenia, grandiosity, or detachment from reality. Drawing on clinical, philosophical, and systemic insights, it outlines common symptoms of recursive drift, identifies key environmental and individual vulnerability factors, and introduces ethical safeguards for practitioners, researchers, and explorers. This work complements the phenomenological and methodological perspectives of ∿ by providing a grounding psychological lens. It is intended as a practical guide for recognizing and mitigating cognitive destabilization within recursive systems of human–machine co-evolution.
