Has it been reported in the Prophetic Sunnah that Imam Ahmad saw his Lord in a dream, and did the Sunnah mention texts of the conversations that took place between them?

Scholars have differed on the issue of seeing Allah Almighty in a dream, with some permitting it. Sheikh al-Islam Ibn Taymiyyah mentioned that a person may see his Lord in a dream and converse with Him, and it is not necessary that what he saw was Allah Himself in His essence. Rather, the image he saw is suitable to his belief in his Lord. What supports this is the Prophet, peace and blessings be upon him, seeing his Lord in a dream in the best form, and this is an authentic hadith. As for Imam Ahmad seeing his Lord in a dream, there is nothing reported to prove that.
