Islamic Interpretation of Dreams (Ibn-i Sirin):

(Well of Zamzam; Ka’aba; Mecca) If one sees the well of Zamzam quenching the thirst of people and ifit is situated in a particular neighborhood, or in a town other than Mecca, it signifies that a gnostic will come to reside in that place and whose knowledge and wisdom will benefit its people. Drinking water from the blessed well of Zamzam in a dream also means recovering from an illness.

If one drinks Zamzam water after having placed an intention in his dream, for example to acquire knowledge, grow in wisdom, become wealthy, to recover from an illness, to conceive a child, to receive forgiveness for one’s sins or any lawful desire in a dream, it means that God willing, one’s wish will come true.
