I am not aware of any specific method or therapeutic approach called the "Raven method" related to dissociative states or dissociative disorders. It is possible that new therapeutic methods or approaches have been developed or gained recognition since then.
If the "Raven method" has emerged or evolved , I wouldn't have information on it. It's crucial to ensure you are using accurate and evidence-based information when dealing with mental health and therapeutic practices.
If you are experiencing dissociative symptoms or have concerns about dissociation, it is essential to consult with a qualified mental health professional who can provide personalized assessment and treatment recommendations based on your specific needs and circumstances. They can guide you through appropriate therapeutic interventions and help you understand the potential role, if any, of the "Raven method" or any other treatment approach in managing dissociation.
