Islamic Interpretation of Dreams (Ibn-i Sirin):
(A leather loop passing under a horseâs tail and is buckled to the saddle.) In a dream, a crupper represents a contemptuous and a lowly guardian who profiteers and takes advantage of his position.
A crupper in a dream also represents a servant who has a secret affair with his mistress.
A crupper in a dream also means money or a money belt.
