What do you mean by "how heavy it is outside the window, and the flowers are broken tonight"?

Pinyin: Chuāng wàI gèng shēn lüzhòng, j ā n y ò lu ò hu ā ché ng zhu.

Interpretation: The night is deep and the dew outside the window is heavy. Tonight, the flowers fell to the ground and piled up into mountains. Between the lines of these two sentences, I feel sad, sad and lonely because I miss my loved ones in the middle of the night and completely ignore them.

The original text is as follows.

I have a quiet dream, I don't know who I can * * *. No one can understand how many secrets there are. The window is deeper and more exposed, and the flowers are cut into pieces tonight. Spring has come and gone without a trace, leaving only a quiet dream-A Quiet Dream by Qiong Yao.
