Dreamer - There is a big influence in your life from your grandmother and mother. The influence comes from the memories and experience we gather unconsciously from being close to someone; the experiences 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 the influence or attitudes you learnt from them is shown in the dream as partly helpful and partly dangerous - the food. So you need to learn new ways of dealing with your wonderful dream baby.
It is innate in women to dream of being creative and giving birth in their dreams. So I believe that such a baby is a very real part of you – though an inner and not always an outer part. This creativity is your potential, and it is a potential that can create a real baby, or in your case a new part or expression of you - the baby.
Example: And then there were the images again of clefts: the earth, female genitals, undersea-ocean crusts opening and something, as yet formless, emerging. This, I suspect, is my creativity in the world.
So do not waste that creativity you have. It can be creative in new ways such as social actions, in caring for others, in creative art work, such as writing or music, or ways beyond counting. Life itself is infinitely creative, look around at all the forms it creates.
The baby is watching you to see what you will do with it - your female creativeness. Take it and love it and explore to see where it will lead you. See
