To dream that you are in a cemetery indicates an end to a habit or behavior. You are experiencing a rebirth. More directly, the dream may symbolise sadness, unresolved grief or your fears about death.

To dream that you are cleaning the cemetery suggests that you are coming clean about your past. In some Asian cultures, a special holiday revolves around surviving members of the family visiting and cleaning the gravesites of the deceased as a way to pay their respects. Thus in this regard, your dream may mean to respect your past and where you came from.
