I have given myself permission to dream about a subject and have experienced that subject in my dreams. Emergent knowledge of the complex comes in many forms. Part of that process is realizing the many things we can not know. For people who can not think in mental imagery must rely on language alone which seems like more of an imitation of reality than the mental picture of the subject. Of course the language alone person would see this differently. I often can see a clear picture of a person's face long before I can recall the name of that person. This would not be the experience of the language only person.
