Dr.  Peter Levine states:  “the (trauma) feedback loop is broken by helping people uncouple fear from immobility” This is done by helping a person safely learn to “contain” his or her powerful sensations, emotions and impulses without becoming overwhelmed. “When clients achieve this, they often describe the physical sensation of immobility in the absence of fear with a mixture of fear and profound relief or,often “as though waking from a nightmare.”
