A Man's Pregnancy
Scholars have stated that if a man dreams of being pregnant, it might indicate an increase in his worldly affairs. If he dreams of having a boy, he might experience severe distress. However, if he has a girl, he might attain goodness, and similarly for dreaming of buying a boy or a girl.
