Depersonalization-Derealization Disorder as Affective Detachment Wrong Attractor: The Observer-Self Dissociation, Emotional Numbing as Persistent Landscape Feature, and the Paradox of Hyper-Self-Awareness Without Self-Feeling

We apply the Displacement Framework to Depersonalization-Derealization Disorder (DPDR), formalizing it as W_DPDR — a wrong attractor of affective detachment in which the individual processes the world from a disconnected observer stance with intact cognitive function but absent emotional resonance. The embodied presence ground state S⁰_presence is defined across four dimensions: emotional resonance with experience, interoceptive grounding in bodily aliveness, sense of agency, and present-moment immersion.

W_DPDR is maintained by medial prefrontal cortex hyperactivation with amygdala hypoactivation — the same neural configuration generating both emotional numbing and the hypervigilance paradox: DPDR patients are hyper-aware of themselves, describing their symptoms in exquisite detail, but this hyper-awareness lacks emotional quality. Nine formal propositions cover: S⁰_presence definition (P1), W_DPDR observer-self dissociation (P2), emotional numbing through mPFC-amygdala inversion (P3), the hypervigilance paradox (P4), the anxiety-DPDR bidirectional cycle — anxiety triggers DPDR as defensive response; DPDR triggers anxiety about the DPDR (P5), the DPDR-Cotard spectrum — DPDR as partial W_cotard with intact reality testing on a severity gradient of affective landscape collapse (P6), substance-triggered DPDR through CB1/5-HT2A pathways (P7), acceptance-based CBT as return path exploiting the paradox that fighting DPDR deepens the observer stance (P8), and the return path paradox — forced presence-seeking deepens detachment; return requires sensory grounding without struggle (P9).

Cannabis-era amplification, adolescent developmental risk, and philosophical consciousness implications are analyzed.
