Сонник: Interpretation 1
To see you own shadow in your dream signifies an aspect of yourself which you have not acknowledged or recognized. It may be a quality about yourself or a part of you that you are rejecting or want to keep hidden. These qualities may not necessary be negative, but can be creative ones. Alternatively, the dream may mean that you are in someone else's shadow. You are constantly being overlooked and are fed up with it. In particular, if the shadow in your dream is white, then it is your subconscious' way of highlighting the shadow which is often overlooked.
