Do recurring dreams about a girl the questioner wishes to marry, including dreams seen by the questioner and his relatives, indicate the possibility of his marriage to her?

Recurrent dreams may be an indicator of your marriage to the girl, but this cannot be stated with certainty. If the girl is pleasing in her religion and character, try to convince her father to agree. If he agrees, then so be it. Otherwise, do not obligate yourself to her, for Allah may facilitate for you someone better than her, in fulfillment of His saying, "And perhaps you dislike a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allah knows, while you know not." It is advisable to seek counsel and perform Istikhara concerning marriage.
