In my previous blot post, “On Being a Remainder” (http://www.psychologytoday.com/blog/feeling-relating-existing/201309/being-remainder), I described two essential features of a traumatized state—a collapse of the significance or meaningfulness of the everyday world and an uncanny feeling of alienation or isolation from that world. In Being and Time the philosopher Martin Heidegger identified these same two features as being central to the experience of existential anxiety (Angst). In his ontological account of these features, he claimed that they are grounded in what he called authentic (nonevasively owned) being-toward-death. Existentially, death is not simply an event (croaking) that has not yet occurred. Rather, it is a distinctive possibility that is constitutive of our very existence—of our intelligibility to ourselves in our futurity and our finitude. It is “the possibility of the impossibility of any existence at all.” Because death is both certain and indefinite as to its “when,” death and traumatic loss are possibilities that always impend for us as constant threats, robbing us of the tranquilizing illusions that characterize our absorption in the everyday world. The appearance of existential anxiety indicates that the fundamental defensive purpose (fleeing) of everydayness has failed and that authentic being-toward-death has broken through the evasions that conceal it. Torn from the sheltering illusions of the everyday world, finite human existing is inherently traumatizing (http://www.routledge.com/books/details/9780415893442/).
