If you dream of leeches, be alert — people around you may be quietly working to undermine your interests and drain your resources. If the leeches are being used on you for medical treatment, brace yourself for a serious health concern arising within your household, even if you personally remain unaffected. Seeing leeches applied to someone else suggests that illness or hardship is approaching a person close to you. If the leeches bite you in the dream, heed it as an urgent warning: danger may be lurking in places you would never expect, and vigilance is your best protection.
