What an odd coincidence that I just experienced Deja Vu this morning. I was a having a conversation with my wife, and about two sentences in I was able to predict the next three, because this exact conversation had happened to us in one of me dreams month ago.
I was a mundane conversation about her preparing to go out with our child. But it isn't something that would be "normal" because she was meeting with a very specific friend, which was part of my recall of the event.
But how certain are you that you were able to predict the next three? Did you stop her from saying them and write it down, and let her continue (without letting her see what you wrote down or watching you write it down)? If not, then you may just have been listening along with her and misinterpreted your own thoughts as having "knew ahead of time" what she was going to say, when all you were actually doing is simply comprehending it. It's a very real possibility unless completely ruled out like this.
