This research aims to comprehend the privileged role of angst in the existential analytics based on Martin Heidegger’s work Being and Time. The focus of this study lies precisely on the privilege of this role for those who can be anguished, ie, the human Dasein. This prerogative is supported by the possibility of an existential transformation. Once the anguish suspends determinations that we are. This suspension makes room/space for other ways of being, which means that another relation with the existential space may arise. In the average everydayness there is a narrow space for something different appears. In fact, in this quotidian way of being a narrow space is given to the space where the existence itself is constituted. This disclosure will come just when we are anguished. This means that the angst brings a space, but does not guarantee that something different can emerge from there, which means that automatism can always be retaken. The privileged role pursued in this research raises from the possibility of two anguish’s voices: the first one is related to break of the automatism, while the second one points to an acceptance of angst as an existential possibility. It is just when this two voices are listened that can occurs an existential transformation, which means an apprehension and a transparency related to our authentic way of being.
