Islamic Interpretation of Dreams (Ibn-i Sirin):
A cross in a dream represents a high ranking person who is worthy of respect or it could represent a religious person. Carrying a cross in a dream could mean marriage, or an unsuitable marriage, or begetting a son.
Seeing a cross in a dream also could mean adultery, rape or conceiving a son in sin.
Seeing a cross in a dream is also interpreted to mean death, opposites, opposition, war, fight, distress, temptation, lies, false testimony or slander.
