We have all had minor traumas and have learned to adjust to them, like a cat whose paw is accidentally stepped on but who appears to be emotionally uninjured, although it may be wary of our feet in the future, But, like the cat in our first example, if the trauma is great enough, a traumatized human will never be exactly the same human, either!
In the following Ted Talk, Sasha joseph Neulinger speaks about surviving multi-generational sexual abuse and how it can constructively influence our choices for the future.
Clients sometimes ask to be hypnotized in order to find out whether or not they have been molested or abused in other ways. Hypnosis is not used to help in the recovery of past traumas because there might be so much emotion associated with these memories that the client may be overwhelmed by them. Indeed, the relaxation and security of the hypnotic setting itself may occasionally be sufficient to bring about the recall of childhood traumatic events, possibly traumatizing the client all over again and making recovery even more difficult than it was before. Clients are not even encouraged to talk about their childhood trauma unless they feel comfortable in doing so. There is also the danger of "false memory syndrome," or the tendency of the imagination to construct events which never actually occurred, which caused great anguish in the past, before this phenomenon was formally recognized.
I like to recommend Babette Rothschild's The Body Remembers: The Psychophysiology of Trauma and Trauma Treatment for clients in my practice who like to read about trauma treatment and who themselves have been victims of trauma. She writes with great clarity, but some familiarity with the professional literature is usually helpful.
