A trauma-focused therapy (Shapiro, 1987) using bilateral stimulation — eye movements, tapping, or tones — while recalling distressing memories, to help the nervous system reprocess them.
You hold the memory of the incident in mind while the therapist moves a finger left-right across your visual field for ~30 seconds. You report what you notice. Repeated over sessions, the memory loses its physiological charge — you can think about it without the body re-enacting the threat.
