I heard Messenger of Allah ﷺ as saying: So far as Lailat-ul-Qadr is concerned. some persons among you have seen it (in a dream) in the first week and some persons among you have been shown that it is in the last week; so seek it in the last ten (nights).  

مسلم:١١٦٥dوَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى أَخْبَرَنَا ابْنُ وَهْبٍ أَخْبَرَنِي يُونُسُ عَنِ ابْنِ شِهَابٍ أَخْبَرَنِي سَالِمُ بْنُ عَبْدِ اللَّهِ بْنِ عُمَرَ أَنَّ أَبَاهُ ؓ قَالَ

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لِلَيْلَةِ الْقَدْرِ إِنَّ نَاسًا مِنْكُمْ قَدْ أُرُوا أَنَّهَا فِي السَّبْعِ الأُوَلِ وَأُرِيَ نَاسٌ مِنْكُمْ أَنَّهَا فِي السَّبْعِ الْغَوَابِرِ فَالْتَمِسُوهَا فِي الْعَشْرِ الْغَوَابِرِ
