I used to see dreams, but the hadith transmitted on the authority of Laith b. Nuʿman, the words of Abu Salama at the concluding part of the hadith are not mentioned. Ibn Rumh has reported in the hadith: "He (one who sleeps) should change the side on which he had been lying before."  

مسلم:٢٢٦١eوَحَدَّثَنَاهُ قُتَيْبَةُ وَمُحَمَّدُ بْنُ رُمْحٍ عَنِ اللَّيْثِ بْنِ سَعْدٍ ح وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى حَدَّثَنَا عَبْدُ الْوَهَّابِ يَعْنِي الثَّقَفِيَّ ح وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ كُلُّهُمْ عَنْ يَحْيَى بْنِ سَعِيدٍ بِهَذَا الإِسْنَادِ وَفِي حَدِيثِ الثَّقَفِيِّ قَالَ أَبُو سَلَمَةَ فَإِنْ كُنْتُ لأَرَى الرُّؤْيَا وَلَيْسَ فِي حَدِيثِ اللَّيْثِ وَابْنِ نُمَيْرٍ قَوْلُ أَبِي سَلَمَةَ إِلَى آخِرِ الْحَدِيثِ وَزَادَ ابْنُ رُمْحٍ فِي رِوَايَةِ هَذَا الْحَدِيثِ وَلْيَتَحَوَّلْ
