When our system has been "traumatized" it means we have been taken to the point of overwhelm. When we are overwhelmed, we quite literally take a step back, often with an inhale, and freeze. Our thinking brain goes offline, and our body brain starts encapsulating everything into a "hologram".
Everything that happens next is encapsulated and stored, isolated so that we are protected. It is encoded into what we could call an icon. This icon only needs one fragment of the primary event inorder to bring up everything, just like a hologram only needs one fragment to bring the entire image up, or our body only needs one cell to bring our entire DNA up and clone us.
With the best of intentions our bodies have been assisting us in surviving what we didn't understand or couldn't comprehend. During subsequent days, months, years, our system might get "triggered" by some fragment of the original trauma, and we are left reeling from a cascading jumble of emotions that seem unrelated to, or out of proportion for, the external event.
Trauma is most often about violation. Violation is most often about boundaries. There are many types of boundary violations. An insufficiently explained medical exam can traumatize a young child. This does not mean it was a sexual violation. NOT all violation is sexual. But all violation is a trauma event.
Unfortunately newly trained psychics tend to code violations detected in the body memory of another, as sexual violations. This is not always the case. The body remembers though, that something happened, and the important thing is to clear the trauma from the reactive body. The story is much less important than healing the body memory so that we are able to go forward with our lives.
Please don't accept a "psychic's" interpretation of your past. Trust yourself.
