Playing Music at the Imam's Door
Scholars have said that seeing oneself playing musical instruments like the oud, tanbur, or cymbals at the Imam's door, and dancing, may indicate gaining authority and power if the dreamer is worthy. If not, it may point to fabricating speech or lying. It has also been said that the mizmar (flute) alone symbolizes authority.
