Commonly experienced as
- People describe suddenly feeling transported back to the traumatic event — not as a memory but as a present experience. Sights, sounds, and bodily sensations of the trauma return without warning. The world around them may feel unreal (derealisation) or they may feel unreal within it (depersonalisation). Duration varies from seconds to hours. The aftermath involves significant disorientation, exhaustion, fear, and shame. Many develop complex avoidance behaviours to prevent triggers, progressively shrinking their life.
