This is why I listen to audiobooks when trying to fall asleep. If I can't fall asleep, I'd rather someone read me a bedtime story than have my own thoughts bouncing around the inside of my head all night.
I do that as well, I tend to listen more to non-fiction since many fiction audio books have "acting" in them instead of just reading :(
I like there to be a little acting. I've had books where the delivery was fairly monotone, with no difference in delivery between scene description and a character speaking in anger or surprise etc. It sounds weird, wooden & stiff. I can see how that has the potential to be more distracting when trying to get to sleep though.
