My dad is 86 and starting to fail physically and somewhat mentally. For the first time he is talking in his sleep about his experiences in a MASH unit during the Korean War. He never volunteered much about what he went through there. Mainly when he talks he is just griping about being a soldier which I find kind of humorous. But he has started to talk about having to be on point all the time on missions to retrieve bodies at night. He says that they can't use any light because it would draw enemy fire. I don't know...
