I have the weirdest dreams.
OK. I don't remember everything, except this had to do with animals (dogs, mostly) and their behavior/training. There was me (I think) and someone else, and we had a problem dog. One of us said "Well, if we want to try to fix him, we need to write the code in the book, and that will reprogram him."
So the Someone Else opened the special book and wrote down two 4-character 'words'. The dream immediately switched to the dog's point of view and it thought "Well, if I knew I could just write in the code, I would have done it myself." And in the weird semi-lucid way I have in dreams, I thought "Too bad that this isn't real. And those codes look like Dragon Cave codes."
So yeah. Wish I could remember the rest-- this is what stuck with me.
