As-Salaam alaikum,
A Sahih hadith mentioned in al-Qari's commentaries and also cited in Sahih Bukhari, al-Tirmidhi with 3 chains of narration in the book, 'PROPHETS IN BARZAKH'- (page 139), the Prophet, Sallallahu alaihi Wasallam, said:-

"My Lord came to me in the best form"- the narrator said: I think he
said: 'In my sleep' and asked me over what did the Higher Authority
(al-mala' al-a'la) vie, and I said I did not know, so He put His Hand upon
my shoulders, and I felt its coolness in my innermost, and knowledge of
all things between the East and the West came to me."

Scholars of the Ummah interpreted this account of the Prophet's vision as meaning that, whether it took place in his dream or in a wakeful state, the Prophet Sallallahu alaihi Wasallam, saw Allah Ta'ala in the real sense. Al-Razi and al-Bayhaqi interpreted the placing of Allah's hand on the Prophet's shoulders as a demonstration of Allah's extreme consideration and love for Sayyadina Muhammad, alaihi salaat was-salaam.

The placing of the Hand on the shoulders refers to an outpouring of love and Divine Mercy into his heart, and the coolness described is the completion and perfection of his knowledge,as described by the Prophet himself when he said: " I knew all things between the East and the West."
