Many years ago i read a short story about a drug that made the addict trapping in an endless wake-up-in-the-sleep-and-think-this-is-real-awakeness, I don't remember author's name but the translator's name was "shahriar bohrani".
I saw 1408 last night it was a good movie and remind me of that story, besides i knew John Cusack from Identity and i liked that movie so Cusack is in my favorite actors list.I recommend the movie to you if you like horror movies.
