Well, I'm mighty glad I came onto the Downs today! That sounds worth looking into. I have the feeling that recurring dreams are not good for you, especially recurring nightmares, and I have ones which I remember all day long.
The more I read about Tolkien and the more I read of some of his characters and some of their own mental torments, I'm sure Tolkien himself had some form of PTSD after his war experience as he certainly understood the torments you can go through - recurring dreams, a 'doomy' outlook, fascination with fantasy etc. It seems he
understood. Luckily he appeared to have a capacious memory.
