It's an interesting question, starry. I suspect a lot of illnesses are connected. PLs are written on our souls, and our bodies. My thought was that no "real" shrapnel is in his brain, and it's a shadow, or echo that his body produced as a result of a Civil War injury. Our generation struggled with the concept of war because of Viet Nam. Speaking of Rose Rooney, I suddenly connected another person from my current life to hers. Many years ago, I briefly dated a man who had that feeling of instant familiarity that we all get occasionally. He came into my life almost concurrently with my present husband. My soul recognized both of them, and I had to make a choice. I chose my husband, but the young man and I discussed the "next life". He walked out the door, but somehow I felt we'd made a "date" for another time and place. Last week, I suddenly made the connection between he and Rose. In this life, he was from one of the Civil War "border" states, and a career military man. I remember thinking about the Civil War when I met him, but hadn't remembered Rose yet. I have good PL recall, but have trouble connecting current life people with those I knew then, so it's good when I can piece relationships together.
