Cutting the Male Organ
Scholars have said that seeing the male organ cut off and thrown away in a dream might indicate the dreamer's death, the cessation of his lineage, or the death of his son. If the dreamer has a daughter and sees his male organ cut off and placed on his ear, his daughter might give birth to a girl not from her husband. Furthermore, for a ruler, its cutting signifies dismissal, and for a warrior, defeat.
