Do you know, the sufi Sakhi Shabaz Qalander? Nicked named Ali Shabaz Qalander? His actual name is Usman  (much to ponder on here)
must share a dream someone saw and shared with many people, he said he saw both Prophet Muhammad PBUH and Ali AS praying together, and what was interesting was the way they were praying.
Muhammad PBUH with his hands open and Ali with his hands closed like Ahle Sunnah.
Reminds me of the Hadith saying if you hear anything nice you should accept it and don’t doubt it but anything negative you must investigate and question.
As far as above dream is concerned I only see positive vibe, an invitation to all Muslims to come out of this trivial difference and embrace the essence and spirit of Islam.
All the best buddy
