Islamic Interpretation of Dreams (Ibn-i Sirin):
(Astray; Heedlessness; Ingratitude; Irreligious; Profane) In a dream, disbelief represents a rich person or becoming one. Disbelief in God Almighty in a dream also means illness, injustice or causing harm to others.
Acting silly or impudent or stupidly, or being censured or discredited in a dream also indicates profanity and disbelief in God Almighty. Going astray in a dream means committing a sin or making a mistake. Making a mistake in a dream also signifies heedlessness in wakefulness.
Ifoneâs profanity becomes public knowledge in a dream, it means that he will commit a forgery or make false testimony in court. Disbelief in a dream also means ingratitude or it could denote the state of a sick person when he lies in his deathbed and awaits for his soul to be taken back to its Lord. Disbeliefin a dream also maysignifycommittingthe unforgivable act of suicide.
