Did you felt powerless or full of anger and aggression? Would you like to go into a small mouse hole to be not seen or shouting with some one?
Than your autonomous nevus system has control over you.
The evolution shows that human beings (mammals) can stop such reactions through eye contact, calming voices, deep breathing, and a friendly face you are looking into. This is called co-regulation, which happens through the nevus vagus specially the smart vagus. This is the Polyvagal Theory from Stephen W. Porges.
