I didn't read it before it was edited so you're fine.

I think having him wake up from a dream would be too cliche. A more sci fi ending would be more appropriate I think, since that's the feeling I get from this story for some reason.

If you enjoy oldish movies, definitely give Johnny Got His Gun a watch. The book is supposed to be great as well, a classic by many accounts. I really like the message of the movie. Very novel way to make an anti-war movie/book.
