Islamic Interpretation of Dreams (Ibn-i Sirin):

Seeing spikes of grain in a dream means money and profits that will multiply. Green spikes of grain in a dream represent prosperity and a good harvest, while dry spikes of grain mean drought.

Spikes in a dream also represent the days, months and years of one’s life, or the wealth contained in this world, its natural resources, or its coffers. Carrying a bunch of green spikes in one’s hand in a dream means knowledge or profits. Collecting spikes of grain from different spots in a farm one recognizes in a dream means that he will receive regular payments or a wage from the owner of that farm.
