Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “When the end of time approaches, the dream of a believer can hardly be false. The dream of a believer is one of forty-six parts of prophecy and whatever is from prophecy cannot be false.”
In another narration, the Prophet said, “The most truthful of you are those with the truest dreams. There are three types of vision. The righteous vision is glad tidings from Allah, the distressful vision is from Satan, and the vision arising from oneself. If one of you sees something he dislikes, let him stand to pray and not speak to people about it.”

عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا اقْتَرَبَ الزَّمَانُ لَمْ تَكَدْ تَكْذِبُ رُؤْيَا الْمُؤْمِنِ وَرُؤْيَا الْمُؤْمِنِ جُزْءٌ مِنْ سِتَّةٍ وَأَرْبَعِينَ جُزْءًا مِنْ النُّبُوَّةِ وَمَا كَانَ مِنْ النُّبُوَّةِ فَإِنَّهُ لَا يَكْذِبُ
في رواية أخرى قال وَأَصْدَقُكُمْ رُؤْيَا أَصْدَقُكُمْ حَدِيثًا وَالرُّؤْيَا ثَلَاثَةٌ فَرُؤْيَا الصَّالِحَةِ بُشْرَى مِنْ اللَّهِ وَرُؤْيَا تَحْزِينٌ مِنْ الشَّيْطَانِ وَرُؤْيَا مِمَّا يُحَدِّثُ الْمَرْءُ نَفْسَهُ فَإِنْ رَأَى أَحَدُكُمْ مَا يَكْرَهُ فَلْيَقُمْ فَلْيُصَلِّ وَلَا يُحَدِّثْ بِهَا النَّاسَ
