Islamic Interpretation of Dreams (Ibn-i Sirin):

(Safety pin) In a dream, a pin represents miseries and wretchedness.

If the pin does not have a head in the dream, then it represents someone who offers invaluable services for a small compensation, or it could mean starting a married life with little furnishings.

Apin in a dream also represents a renowned brother, or a companion who defends his friend.
