When something appears frozen in dreams it has been rendered immobile and usually requires some spiritual effort to free it from its rigidity.
Psychological / emotional perspective: To be freezing something – for instance food – suggests that we are attempting to preserve an emotion or feeling, perhaps to keep a memory pure. It may not be appropriate to do this, however.
Material aspects: In the mundane world a project may be ‘frozen’ either because of time constraints or to prevent it degenerating. This may translate itself in dreams as something being frozen. Consult the entry for ice / icebergs / icicles for further help in interpretation.
