Islamic Interpretation of Dreams (Ibn-i Sirin):

(Black pepper; Hot pepper) Pepper in a dream represents security money that insures the capital investment. Eating pepper in a dream means drinking a lethal drink or a bitter tasting medicine, or falling victim to a bad spirit, or earning money with commendation though through hard work. Pepper in a dream also means money if it is not used as food. Otherwise, if one eats pepper in his dream, it means distress or dismay.
