There is this book that I'm currently reading called "The Vanishing". When ever I'm done with a few chapters and take a nap I always find myself haveing a lucid dream. The first time this happened in my dream I was getting off the couch and opening the door for my brothers friend who was supposed to be coming shortly. After the dream I woke up to my brothers friend at the door. Has this happened to anyone having a lucid dream brought on by a book?
