Understanding Trauma — A Clinical Overview
Trauma is the wound that remains when an experience exceeds what the mind and body could process at the time. The event passes. The wound does not.
The nervous system, unable to complete its natural processing cycle, keeps the experience live — available, intrusive, ready to be triggered by anything that resembles the original conditions. The person is not remembering the past. In a very real physiological sense, they are still in it.
