Existential origins of endogenous and exogenous psychosis: A phenomenological inquiry into uncanny and twilight atmospheres

This article explores the distinct characteristics between early stages of endogenous psychoses and substance-induced psychoses through a structural phenomenological approach. It focuses on how specific atmospheric conditions influence the subjective experience of individuals affected by these conditions. By examining the distinct emotional landscapes associated with psychosis, the study aims to clarify how these atmospheres alter perception and interaction with the world. The research highlights two primary atmospheres: the sense of estrangement and existential dread often present in endogenous psychoses, and the initial allure that can lead to disorientation and fear in substance-induced states. These atmospheric experiences are further analyzed in terms of their intersubjective and temporal dimensions, revealing their profound impact on the perception of self, others, and reality. The study provides insights into the transformation of reality experienced by individuals navigating these complex psychological states and underscores the value of phenomenological approaches in enhancing our understanding of psychopathological experiences. This perspective aims to contribute to more accurate differential diagnoses and foster greater empathy for those affected by psychosis.
