In acting, you add something. The line is just "I want a donut". What you actually do is go to your own past experience. You find the time you wanted a Barbie doll, your mother didn't give it to you, and then you never saw your mother again. That's really traumatic to you.
So you place it into "I want a donut", and now it has massive stakes. I must get this donut no matter what. When you don't get the donut, you're devastated, because you've tagged your past meaning, your past experience that was traumatic, to this one.
Your body does the same thing all day. Why you get triggered so easily.
Detriggering is exactly the opposite. We take where you have attached meaning, and we take it away.
