Hi Yoma – I don’t get the feeling that you encountered ‘danger’. I say this for several reasons, first because I have two similar dreams – “My dog tramp took my right hand firmly in his mouth and led me very purposefully.” Secondly the dog left a circle mark on your hand; and thirdly because the dog was white and met you in the forest.
They are all positive symbols in your dream - White animals: Urges and sexuality that have been accepted or integrated with conscious activities. This means urges that at one time you were in conflict with or anxious about, and have been transformed in urges and feelings that are acceptable parts of your present life. They become available and creative energy.
Forest - If you are in or exploring the forest it shows you becoming aware of the level of yourself that is usually drowned out by your daily life or civilized activities. You will be more aware of meeting your internal animals. This is the country of dreams and the unconscious. In the forest you are in touch with the forces and wisdom of Life.
Circle - Completeness, wholeness, all of the parts of our being, body, soul, spirit. It also represents the universe as a whole, harmony, symmetry. Sometimes symbolises an enclosure or restraining influence, or protection, and stands for the womb, or female sexual organs. May also represent emptiness, receptiveness, or a fertile condition.
You start the dream in nature, in a workshop for architecture - Here is the image of the process or function in us that plans, that designs in a creative and perhaps considering way. It may be about plans for a better or different living condition, or about business or even a relationship. The architect is also pointing to a process of checking and directing progress.
In all it is a very positive dream, in which your socialised natural urges impresses on your hand how you express yourself in action or relationships; your grasp of life, of ideas, of opportunities, and it shows that your efforts are or will be made whole.
But your mum is the anxious worried you, the attitudes you probably gained through being raised be her. You learned to counter this influence because your childhood was one that was full of nature and living – the forest where you meet your internal animals. See
