I dreamt of marrying a stranger. I saw him for first time in my dream and fell in love with him that too at the time of marriage. I can still remember his face and am hoplessly in love with him. will I be able to find him
It seems you have already decided the meaning of the dream, however unlikely your conclusions may be. You have already told us you think you've encountered a real person, with whom you are now in love, and want to find this person to marry them.
Faces that you see in dreams are always the faces of people who you have seen before. It is most likely that you saw the person the face belongs to, the day or a few days before you had that dream. Maybe you could retrace your steps and find the person.
