    • traumatic event persistently reexperienced in at least 1 of:
    • recurrent and intrusive distressing recollections of event
      • recurrent distressing dreams of event
      • acting or feeling as if event were recurring
      • intense psychological distress at exposure to internal or external cues that symbolize or resemble an aspect of traumatic event
      • physiological reactivity upon exposure to internal or external cues that symbolize or resemble an aspect of traumatic event
