I have a close friend that I've known for over 20 years that I believe suffers from some type of disorder where he cannot differentiate between reality and stories he makes up in his head. He's a normal, functioning adult but when he speaks about past experiences his versions of stories change dramatically and become more exaggerated over time. He did two uneventful tours in Iraq with the Army 10 years ago and I know nothing significant happened because he told me each time he got back that he never saw combat. Every year since then he has new, crazy stories that supposedly happened while he was over there. Now he speaks of witnessing a little girl executed and of soldiers being kidnapped from the base. Crazy stuff that obviously never happened but he speaks of them in detail and with passion. He suffers from PTSD over these memories that never actually happened. It's not just his Iraq deployments, he does this with everything. I've known him since we were 15 and he's always been like this but he seems to be getting worse. He's already seeing a therapist over his PTSD but I believe he needs to see a psychiatrist and be medicated. What could be wrong with him? How do you convince someone that their memories are made up?
