First of all, before I put my reply, this is not meant to be mean.
Why would you want to be put into a book, it is paper and ink, what you want is to be put into the setting of a book. To do this you couldastral project into one of the lower planes where your thoughts appear and "make" your book setting. or when you have alucid dream make your book world. Or if your like me, when you read it kind of puts you into a different world, when I read I can see, hear, feel, the book. I always confuse real TV and books, and even real life and books. It's confusing but I love it. Books are my escape, once you read enough, you kind of get extra senses so you can escape into books, its pretty amazing.
i know how to do that. relax on your bed. hold the book above you. read it till the end. put the book ontopof your head. sleep. you will have dream about the story. its your own power to change the storyline. but often when someone try to control their dream they will wake up.
