I'm sure you'll learn more from the PTSD forum, but I can tell you I really connected with what you said here. Flashbacks, hallucinations and not even remembering how I made people around me hurt or even scared sometimes. While that isn't every time or every week (sometimes, it is getting a little worse lately), it's enough to be a problem in so many aspects of my life. Hallucinations with PTSD usually does mean that it's severe, when it hits your family and home it demands to be taken care of (treated) until it destroys a relationship. The illness -- I prefer to say injury -- shouldn't be taken lightly. EMDR is one of the therapies used to help work past the memories and a therapist would be able to tell you more. You're not alone, there's research to be done, but what you described is more common than most people care to admit.
