traumatic dreams are unlike ordinary dreams. In form, these dreams share many of the unusual features of the traumatic memories that occur in waking states. They often include fragments of the traumatic event in exact form, with little or no imaginative elaboration.
Herman establishes the defining formal features of trauma dreams—literal repetition, absence of elaboration, atypical sleep-stage occurrence—grounding them in altered neurophysiological organization rather than ordinary dream processes.
