What is the interpretation of terrifying dreams involving jinn and possessed people, which occur despite commitment to reciting the remembrance of sleep (adhkar al-nawm) and the Quran?

These visions should not trouble you; their remedy is easy. You should seek refuge with Allah from the evil you see, turn over to your other side, and not tell anyone about them, and they will not harm you.

You must strengthen your trust in Allah and your reliance upon Him, and have a good opinion of Him. These visions are merely dreams or delusions from Satan. So, do as we have advised you to ward off their harm, rely on Allah, and strive in supplication to Him to avert these matters from you.
