This text is a testimony of my experience of psychosis. I do not claim to give a definitive explanation but rather to try to illustrate how easy it is to slide from a “normal” discourse into an “abnormal” one, to slide into an all-embracing psychosis (all-embracing because it entails both affect and reason) without being aware of it. My psychosis was characterized predominantly by a wide-spread delusional system with hallucinations less prevalent. I have tried to tell my story chronologically and objectively. Full objectivity is of course an illusion in this case, because of the personal nature of the article , but I have tried to avoid romanticism where possible. With this personal story I attempt to present a “small phenomenology of my psychosis”.
