In a dream it signifies sudden death if there is no cause for it. Rage in a dream may signify committing scandalous deeds and illnesses, because of the change in the enraged person's state when he is furious.
Whoever sees that he is enraged at someone, his affairs will turn against him and his wealth will go, because of His saying, the Exalted:
وَرَدَّ ٱللَّهُ ٱلَّذِينَ كَفَرُوا۟ بِغَيْظِهِمْ لَمْ يَنَالُوا۟ خَيْرًا ۚ وَكَفَى ٱللَّهُ ٱلْمُؤْمِنِينَ ٱلْقِتَالَ ۚ وَكَانَ ٱللَّهُ قَوِيًّا عَزِيزًا
“And Allāh repelled those who disbelieved, in their rage, not having obtained any good. And sufficient was Allāh for the believers in battle, and ever is Allāh Powerful and Exalted in Might.”
Quran 33:25 · Saheeh International
Rage is also poverty and the squandering of wealth.
