From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Shout" (page 388).
Shouting at a gathering of people in a dream means winning the title of a statesman, authority and power in an election, or presiding over people. Ifone sees himself shouting alone in a dream, it means that he will lose his power and his words will have impact. Shouting in a dream also denotes social turmoil, agitation caused by war, an earthquake, the drowning of a ship, or the spread of a new disease that will force people to turn to God Almighty for help. (Also see Calling someone)
