Islamic Interpretation of Dreams (Ibn-i Sirin):
Eating pistachio in a dream means earning blessed money.
A pistachio tree in a dream represents a courageous and a generous man. Pistachio itself in a dream means money. Plucking and eating fresh green pistachios in a dream means hardships and toiling. Dried pistachios in a dream mean evil, an argument or fighting. Eating salted pistachios in a dream means profits from the sea and land, and for a pregnant woman, it could mean that she is close to delivering her baby.
