Islamic Interpretation of Dreams (Ibn-i Sirin):
(bot. Mint; Sweet marjoram; Wild marjoram) Smelling a marjoram plant in a dream means recovering from an illness and enjoying a good health for that year. Planting a marjoram in a dream means begetting a healthy and a beautiful child who will grow to possess a good character. Marjoram in a dream also could mean marriage, or something that will not last.
