Seeing crops in your dream generally symbolizes productivity and success in life. If you dream of a field of crops, it may indicate new opportunities and achievements coming your way. However, if the crops are burning, it signals that some of your plans or efforts may fail. Additionally, dreaming of farming on someone else's land could suggest conflicts or competition in your life.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Crop" (page 103).
Planting in a dream means that one's wife will become pregnant. Ifone sees himself plowing someone else's land in a dream, it means a dispute between the two. A crop that is consumed by fire in a dream means famine and drought. If one sees himself walking through green fields in a dream, it means striving to do good, charitable deeds and leading a devout life not knowing whether his deeds will be accepted by God Almighty or not. As for a married person, planting the fields in a dream means that he will conceive a son, and for an unwed person it means that he will get married, while for a businessman in a dream, it means increase in his profits. Seeing a green crop in a dream means longevity, while a dried crop signifies the near end of one's life. Planting wheat in a dream means charity, and it will multiply one's reward. Spike of grain or ears of grain mean a misfortune or miseries. Seeing barley corns in their fields in a dream means spiritual awakening and a conscious endeavor to do good. If one recognizes his crop in a dream, then they represent his worldly and spiritual deeds. (Also see Farm; Harvest; Planting)
