Dreams are not about what they are about

If you dream about some particular subject it is not often that the dream is about that. Dreams speak in a deeply symbolic language. The unconscious mind tries to compare your dream to something else, which is similar. Its like writing a poem and saying that a group of ants were like machines that never stop. But you would never compare something to itself, for example: "That beautiful sunset was like a beautiful sunset". So whatever symbol your dream picks on it is most unlikely to be a symbol for itself.
