The Pretense of Not Hearing
Scholars have said that whoever sees themselves listening and then pretending not to hear in a dream, this may indicate lying and getting accustomed to it. This vision might suggest arrogance towards the truth and refusal to accept it, based on a Quranic verse describing those who hear God's verses yet persist in arrogance as if they never heard them.
