YOU SAID:
I thought my heart was detached from all the sunlight of our past
INTO JAPANESE
私の心は過去のすべての太陽から切り離されていると思っていました
BACK INTO ENGLISH
I thought my mind was cut off from all past suns
INTO JAPANESE
過去のすべての太陽から私の心は切り離されたと思った
BACK INTO ENGLISH
I thought my mind was cut off from all past suns
That didn't even make that much sense in English.
