Definition: Re-experiencing symptoms are a specific cluster of PTSD symptoms. These symptoms include:
- Frequently having upsetting thoughts or memories about a traumatic event.
- Having recurrent nightmares.
- Acting or feeling as though the traumatic event were happening again, sometimes called a "flashback."
- Having very strong feelings of distress when reminded of the traumatic event.
- Being physically responsive, such as experiencing a surge in your heart rate or sweating, to reminders of the traumatic event.
