Regarding the meaning of よに a song...
 

Dear All,

I have a question about the meaning of よに in the lyrics below. The lyrics are from a song called "そんな空には踊る馬".

青い天井がめくれて　私はうかんだ
生まれたばかりの三日月が　まわるよに　ほほえむ
ああ　私は夢をみてる

What I am confused with is that since ように and よに can be the same sometimes (According to 大辞林: https://kotobank.jp/word/%E3%82%88%E3%81%AB-406383), I cannot tell if the よに here is a noun or an adverb. I would be very appreciative of any help. Thank you very much for the reply. :)

Best,
Karaage
P.S. My first language is not English, so if I make any mistakes, please feel free to point it/them out. Thank you. :)

"よに:YONI" is shortened form of "ように:YOU-NI;like as" used only in song lyrics. "よな:YONA" also used only in lyrics.

Thank you so much for the reply. :)

So the よに here is an adverb, right?

Thank you very much again for you kind help.

As I'm not good at the English grammatical word for Japanese, "よに:YONI" itself seems to be not adverb but "よに:YONI" makes "adverb phrase" as the main marker which qualifies verb.

In the other hand, "よな:YONA" makes "adjective phrase" which qualifies noun..

Correction:

phrase -> clause
"よに/ように:YONI/YOUNI;like that ..."
"よな/ような:YONA/YOUNA;like as ..."
