Any social structure does build a symbolic world in accordance with its collective organization. Myth is a narration designed about the establishment of the society and the ego of that symbolic world. The psycho-mythology is a kind of interpretation which argues the both evolution and effect of collective culture on transformation of the psyche of self. The myth of Deli Dumrul, based on Islamic transition of Turks, narrates a trauma of a hero living within a Shamanist religion when he just realized his mortality. The root of this trauma is the destabilization of the psychology before the normative sequence of Islam. The reason why that psychology experienced such a quake is because it had been established in a native and Shamanist organization to be alienated by Islamic normative order. The myth of Deli Dumrul could be handled as a problematic object of psycho-mythology as it includes the experiences in process of integration to subjectivity which Turks gained them with participation to Islamic order.
