PTSD all depends on what was the event(s) that caused it. I have PTSD as a result of several events following Viet Nam. One in which I watched helplessly as a man was burned alive by solid propellant rocket fuel, another where I was first responder on a airplane wreck. Followed by the event my arm was crushed and spent the next 3+ years having surgeries. I relive all the events in dreams and try to change the outcome. But, it is always the same.
