I'm study the preconscious and unconscious. Is it possible for some unconscious thoughts in the mind to transfer over to the preconscious and even the conscious. It mentioned the need for food in my book, but couldn't that also fall under one of the other categories, since we consciously say we are hungry or anticipate our hunger enough to make a breakfast, lunch or dinner date? I'm a little confused on this whole varying levels of conscious thoughts. Can someone explain it to me?
