Bag of bones

 I think sometimes a book can parallel your life, and give you ironic hints about future events. Sometimes I edit a novel and find certain similar circumstances happening to me in real life. Not the whole story, just parts. It's like the Stephen king novel, bag of bones, where his manuscript is haunted and gives him hints about a ghost. I think that's a mark of great writing, though not necessarily the type that gets published. 

Now that I think about it, it's not just an issue of "prophecy," sometimes your writing can speak to you, tell your future self good advice you didn't expect. That's good writing.
