What the dream mind knows

Have you ever dreamt that you were reading a book that you really were reading? But when you get past where you have really read, the words are all sort of jibberish and don't make sense? It makes sense to me that you couldn't know what you don't already know, but the dream world is so good at filling in the details on other things, sometimes eerily so, that I find it odd that the mind can't be creative with the ending of the book...

My dream last night was like this, only it was knowledge that I wanted form someone, not in a book. I dreamt that I was at my yoga teachers house early one morning with Patty and he had written something about/to me on the white board and I was trying to read it and I got the idea that he approved of something I was doing or a way that I was thinking, but I couldn't really read it. Patty and I were about to leave when he called my name and came out of the bedroom where he and his wife had still been sleeping. He told me to wait because he wanted to tell me something. He started to talk about what he wanted to get me for Christmas and that he had already figured out patty's gift and it had to do with fulfillment because that it what her training has been about. And then he started to talk to me about all that I wanted to know about life and what I would get form teacher training and I was trying really hard to listen to him, but the words were jibberish and I couldn't hear/understand them. It was something that I really wanted to know, but don't yet know and my mind could not fill in the details. My mind could not know.
