Ticice - Thanks. I believe the mother in your dream is all that you have taken in about her. Most people are often totally unaware of the experience they take in and how it interacts with them when we have lived with or loved someone. In other words the memories and experience we gather unconsciously change us and are not lost. It is part of you and is symbolised in dreams as a person or event. You have taken in millions of bit of memory, lessons learnt, life experiences along with all the feelings or problems met by loving and living with someone and they are what makes you the person you are. Your dreams tend to put all that in the image of the past person when you are dealing with the influences left in you from the relationship.
So your mother is a synthesis of her in you, and is still acting as a source of good information. Is there any truth in what she said? Are you lacking a real purpose? Ask a question of your dreams before you go to sleep - What is my purpose or destiny?
