Flashback
A flashback is a vivid, involuntary re-experiencing of a traumatic event, where the past feels as if it is happening in the present moment.
Definition
Flashbacks are intrusive re-experiencing symptoms in which sensory memories of trauma intrude powerfully into the present. They can involve images, sounds, smells, or emotions and may briefly disconnect a person from their surroundings. Flashbacks are a hallmark of PTSD; grounding techniques and treatment can help.
What it can feel like
- Suddenly reliving a traumatic scene vividly.
- Feeling the fear or sensations from the original event.
- Losing awareness of your current surroundings.
- Triggered by sights, sounds, or smells linked to the trauma.
