sleep weirdness

When putting Josie to bed, I find myself intrigued by the new things she has to say in the dark. I want to know what's really going on and if I can make sense of her words. She speaks with fractures of nursery rhymes, TV phrases, odd stuff we've said and then perhaps jibberish. I almost don't want her to go to sleep, but that defeats the whole purpose of putting her to bed.
