If you experience a fearful dream, blow on your left three times in such a way that a few droplets of saliva come out each time. Thereafter read A’udhubillahi minash shaytanir rajim three times. Also change your position of sleeping. Do not mention this dream to anyone. Insha Allah, no harm will afflict you.
If you wish to mention your dream to anyone, choose a person who is intelligent or who has your interests in mind. This is so that he does not give you any evil interpretations.
