This is correct. It will work away at the past backlog of trauma and difficulty you have experienced. Working bit by bit, it will trim back the accumulated trauma of many lifetimes dealing with the interlopers and creating many stored trauma memories, all of which can be resurrected, viewed by the deep subconscious, and plague the deep subconscious and its concerns about safety and may well give rise to symptoms. This is commonplace and a curse for every human being on a daily basis about something. Anything that rises to the level of a potential lethal consequence, even witnessed happening to others, is a reminder about personal vulnerability and will stir up anything stored in that particular category of events and will have a consequence energetically and emotionally as well. These are healable.
