2. Recurrent distressing dreams in which the content and/or affect of the dream are
related to the event(s). Note: In children, there may be frightening dreams without
recognizable content.
3. Dissociative reactions (e.g., flashbacks) in which the individual feels or acts as if
the traumatic event(s) were recurring. (Such reactions may occur on a continuum,
with the most extreme expression being a complete loss of awareness of present
surroundings.) Note:  In children, trauma-specific reenactment may occur in play.

sponse to internal or external cues that symbolize or resemble an aspect of the
traumatic event(s).

happiness, satisfaction, or loving feelings).
Dissociative Symptoms

from another’s perspective, bein g in a daze, time slowing).
7. Inability to remember an important aspect of the traumatic event(s) (typically due to
dissociative amnesia and not to other factors such as head injury, alcohol, or
drugs).

ciated with the traumatic event(s).
