Books on tape

Anyone ever listen to books on tapes when going to sleep? If so has it affected your dreams? I ask because I have been listening to “Enders Game” the last couple nights as I go to sleep and have been having some interesting dreams based on it. I haven’t been a character from the books and the books don’t play out exactly but I’m a character in that situation in the dreams. I have achieved lucidity twice during them so far but just rode the dream and only took the slightest control since the dreams have been so interesting. Anyway I was just thinking this is an interesting way to shape your dreams how you want them without actually being lucid. I imagine others have thought of this but I didn’t see any other posts on it so I figured I’d bring it up. It seems a good payoff to me, interesting dreams at the cost of a trip to the local library (it has tons of books on tape).
