Dissociation is a trip switch to protect the nervous system from over charging, it is not pathology (a disease) but a life-saving mechanism. It is the symptom of the most highly charged traumatized state. By re-associating, the traumatized person can reconnect with their biological resources. One symptom of disassociation is when someone is able to talk about very emotional or painful material, without showing any emotions or feelings. If someone is disassociated or spaced out then talk to them about concrete things.
