The center that I cannot find is known to my unconscious mind.
I enjoy working with people's dreams. Whenever they appear in a session, they always present rich inner material for that person. Dream dictionaries are never used in my office. (They can be helpful but they are limited).
The main reference point, or interpretation base is that person. I simply ask the guiding questions. What is that related to in your waking life? What do you really feel about the person in your dream? What do you feel the dream is about? And etc.
I kept a dream diary myself over many years, the style of writing still intrigues, delights and yes - informs. It still reminds me of how completely insane I am...Oh but in a good way.
A dream diary holds a personal history that can be helpful down the track as well as the morning after your dream. What are your dreams telling you at the moment?
