if you are referring to a method that is called by a different name or if you provide more context about what the "Raven method" entails, I may be able to provide some information on how it could potentially play a role in a dissociative state or how it might be relevant to mental health treatments.
It's essential to note that when dealing with DID or any other mental health condition, it's crucial to rely on evidence-based treatments and work with qualified mental health professionals who have experience in treating dissociative disorders. Therapy approaches such as Trauma-focused Cognitive Behavioral Therapy (TF-CBT), Eye Movement Desensitization and Reprocessing (EMDR), and Dialectical Behavior Therapy (DBT) have shown to be beneficial for individuals with DID and those who have experienced trauma. Always consult with a licensed mental health provider for appropriate assessment and treatment options.
