Spiritually, any enclosure represents the protective aspect of the Great Mother. Aspects of ourselves that are too frightening, disturbing or private to be allowed full expression are often perceived as enclosed spaces. To be in an enclosed space suggests an exploration of these aspects. To be outside this space signifies a fear of them. In dreams, the defence mechanisms we put in place to prevent ourselves from deeply feeling the impact of such things as relationships, love, anxiety or pain can often manifest as an enclosed space. Restraints and constraints can appear as actual walls and barriers. Consulting the Introduction for information on the Great Mother and also the entries for Barrier and Walls will further help in interpreting your dream.
