The article is a reconstruction of experimental transformations of the perception and experience of the reality in the phenomenological psychopathology of Czech psychiatrist Svetozar Nevole (1910-1965). The problem is treated in relation to the aesthetical problems of the artistic creation and also with regard to the phenomenology of the reality of Alfred Schütz and to the phenomenology of the "alien" (Phänomenologie des Fremden) of Bernhard Waldenfels.
