When you say "they have no idea about what they're about to say" you're talking about conscious thought. I think there is a difference between rational thought (thinking by going through a series of logically connected steps) and intuition, where you can arrive at a conclusion or knowledge of some fact or concept or knowing how to do something, without having gone through those conscious steps. Does one count as "thoughts" any less than the other? People are sometimes so quick to dismiss any subconscious thinking as being nothing more than a very complicated computer, but I couldn't disagree more.
