The Dream Book of Self-Knowledge
- usually holds a secret.
- can be a place, ritual object or magical symbol during the transformations of emotional into spiritual content.
- a shell opening: symbolizes birth, but the opening must never be forced since the contents within, which the dreamer still isn't able to understand and consciously process, would flood him.
- usually a place of the birth of spiritual personifications (spiritual anima emerge from the shell to men, spiritual animus to women).
