Islamic Interpretation of Dreams (Ibn-i Sirin):
(Cow bell; Sleigh bell) Possessing small bells in a dream means a fight, an argument or vain talk known of the person holding them.
Seeing a bell in a dream represents the announcer or the forerunner of a ruler. Generally speaking seeing a bell in a dream means that someone will bring glad tidings.
If the bell is roped around the neck of an animal in the dream, it means travel.
The bells of a church represent people one can seek their advice and follow their opinion. Bells in a dream also represent calling to prayers or preparing to meet one’s enemies, or they could mean the arrival of a caravan or a shipment. Bells in a dream also represent abrogated books of revelations or tampering with God’s revelations or they could represent past traditions.
