I can catch you all of my mind,You are all I think of day an

i can catch you 作为一个部分,all of my mind 作为一个副词短语,修饰前面; you are all i can think of,作为一个部分,实际顺序是 you are all which i can think of,这里省略which,为了押运,实际说话中很多都也省去了的,day and night作为副词短语休息前面.
按照愿意翻译就是:
I can catch you(我能想到你) all of my mind (在我满脑子里),You are all I think of(我所有能想到的只有你) day and night(白天黑夜都是).
翻译得浪漫点就是:
我总能在我脑海中找到你的身影,因为我每天朝思暮想的人是你
