Islamic Interpretation of Dreams (Ibn-i Sirin):
(Debt; Pledge) Making a promise in a dream means indebtedness to the second party.
If one also fulfills his promise in the dream, it denotes his true intention, faith and certitude. Making a good promise in a dream means blessings, profits and longevity. Receiving a good promise from oneâs enemy, or opponent in a dream means evil. Receiving a bad promise from oneâs enemy in a dream means good.
A promise in a dream is a good deed.
The recipient of the promise in wakefulness is the one who makes that pledge in the dream.
