Sleepers — Gerard Houarner

Don't sleep with your eyes open. Don't sleep with your eyes closed. Sleep and wake simultaneously. Enter realities more real than the one you came from. Realities only a shepherd should access. Be prepared, if you walk among the Dolls and Sleepers, that you will never read the same book twice, or pass an identical reflection, even if you should happen to pass the same mirror. For once you are Awakened, you can't pretend to forget, even with the lights off.
