When the nights grow longer, so you fall into sleep, and won't wake up.

当夜晚变得更漫长时，你陷入沉睡，并且不再醒来。

The birds tired resting on the nest ya, grass, insects will fall into sleep;

窗外的鸟声疲倦的停歇在巢桠上，草地里的虫鸣也将陷入长眠；

youdao

I could not fall into sleep that night, pondering on the reasons for my poor performance.

第一次讨论就让我当晚彻夜无眠。我一直在反思究竟自己为什么会这么差劲。

youdao

Lulled by the silence of the carriage and the prospect of alpine rail travel, I fall into a deep, childlike sleep.
