If you see a miller in your dream, it represents a picture of selfishness in your life. A miller is typically identified as someone who chases after material gain and is unhesitant to do anything for it. Particularly, if you dream of an elderly miller, it may indicate selfishness or greed among the people around you. This serves as a warning for you to steer clear of situations where someone might harm others solely for their own interests.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Miller" (page 279).
In a dream, a miller represents a selfish person who is particularly interested in acquiring worldly gains and at what ever price it may cost. If one sees an old man being a miller in a dream, the old man here represents his grandfather, or one's bosom friend and consequently one will prosper and become extremely wealthy from his business. If the miller is a young and a strong man in the dream, then he represents a strong helper. A bakery miller in a dream means that one will attain his own goals through hard work. If one sees himself grinding a sufficient quantity of wheat for two, three, or four people in a dream, it means that he labors for his own need and can barely provide for his family. If the miller is a young man who has gray hair in the dream, then he represents both prosperity and strength. Seeing a miller in a dream also means adversities, fights, a spendthrift, usury, or a hard working guardian. Grinding other grains in a dream means dispelling distress and bitterness from one's heart. (Also see Saffron)
