The dynamic core of your human life is grounded in your feelings, your needs and your drives. When these are bound by shame, your are shamed to the core. As shaming experiences accrue and are defended against, the images created by those experiences are recorded in a person's memory bank. Because the victim has no time or support to grieve the pain of the broken mutuality, his emotions are repressed and the grief is unresolved. As each new shaming experience takes place, a new verbal imprint and visual image attach to the already existing ones forming collages of shaming memories.
Children also record their parent's actions at their worst.
When Mom and Dad, stepparent or whoever the caretaker, are most out of control, they are the most threatening to the child's survival. The child's survival alarm registers these behaviors the most deeply. Any subsequent shame experience which even vaguely resembles that past trauma can easily trigger the words and scenes of said trauma. What are then recorded are the new experience and the old. Over time an accumulation of shame scenes are attached together.
