From a long distance, I saw multitude of children wearing white cloth (as worn in haram) and walking towards a direction after them was multitude of WHITE sheep walking in the same direction. I went inside the mosque to wait for salat and heard a voice making predictions about people.
Wasalam Rabiu, since it’s the time of Hajj, it’s a normal dream. Sheep in dream means generally believers in a town. However, hearing prediction can means that the religious people around you are tainted by some wrongdoing, notably black magic.
