If something flies in a dream

Narrated 'Abdullah bin 'Abbas:

Allah's Apostle ﷺ said, "While I was sleeping, two golden bangles were put in my two hands, so I got scared (frightened) and disliked it, but I was given permission to blow them off, and they flew away. I interpret it as a symbol of two liars who will appear." 'Ubaidullah said, "One of them was Al-'Ansi who was killed by Fairuz at Yemen and the other was Musailama (at Najd) .

حَدَّثَنِي سَعِيدُ بْنُ مُحَمَّدٍ، حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا أَبِي، عَنْ صَالِحٍ، عَنِ ابْنِ عُبَيْدَةَ بْنِ نَشِيطٍ، قَالَ قَالَ عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ سَأَلْتُ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ ـ رضى الله عنهما ـ عَنْ رُؤْيَا، رَسُولِ اللَّهِ ﷺ الَّتِي ذَكَرَ.
