Crypt
A buried room of the dead — the part of the foundation that the living building rests on.
A crypt in a dream is the dream's image of the dead held underneath the structure of the living. Crypts are not graveyards out in the open; they are below the church, supporting it. The dream brings the crypt when something in your present life — your sense of self, your work, your family — is built on a foundation that includes people or events that are no longer present. A crypt visited with respect is the dream telling you the foundation is acknowledged and the building stands honestly. A crypt sealed and forgotten is the dream noting that the basis of your present life includes something you have stopped visiting, and the building is starting to feel rootless.
