Question:
A few nights ago I dreamt that someone I know passed away. Following this a crowd gathered and then lots of people were in mass grave being drowned by police. They were searching for males, they took my brother and I went as well and then I woke up.
Answer:
Drowning means shahada (martyrdom) and the dream is about cleansing and intercession for lots of people in sha Allah.
