A deep understanding of the subjective experience of time in traumatized individuals may require a comprehensive framework that takes into account both psychoanalytic and phenomenological contributions. Referring to the retroactive interpretation of past experiences, the concept of Nachträlichkeit is critical to analyze how trauma can be signified in the form of the après-coup, in which the original traces of traumatic experiences are signified only at a later time. Trauma alters the temporal sequence of past, present, and future, thus leaving the psyche in a time-shifted dimension, where the shadow of the past extends over the present, and the unbearable present hinders growth and development. A clinical vignette is presented to illustrate how trauma can disrupt the temporal nature of subjective experience by reshaping the meaning of psychic events. Ultimately, trauma treatment aims at inscribing the person's experience into a unified and coherent self-narrative.
