Islamic Interpretation of Dreams (Ibn-i Sirin):

(Throng) Seeing a crowd gathering or standing in line or a large number of people suffering in wretchedness in a dream means increase in one’s power, rising in station, gaining fame and recognition.

If a merchant or a business man sees a crowd of people in a dream, it means growth in his business and increase in his clientele.

If a preacher sees that in his dream, it means that his followers will grow in number.
