Is it permissible for me to ask: After my uncle’s death, I started to feel terrified and afraid, and as if I am bound, and I feel pressure and wake up scared, so what should I do?

We advise you to regularly recite the remembrance (dhikr) before sleep, and to dispel fear by seeking refuge in Allah, holding fast to Him, fortifying yourself with invocations, continuing your studies, maintaining a good opinion of Allah, being certain that He is the Protector of those who rely on Him, and supplicating when frightened with the words: "I seek refuge in the perfect words of Allah from His wrath and punishment, from the evil of His servants, and from the whisperings of the devils and their presence." Indeed, they will not harm him.
