Chicks cheep and I can't count sheep to sleep.

小鸡唧唧喳喳，我数绵羊也睡不着。

I can not sleep, so I count sheep.

我不能睡觉，所以我属羊。

Chicks cheep and can't count sheep to sleep.

小鸡唧唧喳喳，数绵羊也睡不着。

Midnight wakes is no longer count sheep urged to sleep.

半夜醒来不再是数羊催促睡觉…

Subjects who instead imagined "a beach or a waterfall" were forced to expend more mental energy, and fell asleep faster than those asked to simply count sheep.

让实验者想像“瀑布”、“海滩”都会让他们脑力更加疲惫，结果就是他们比数绵羊的人睡着的更快。
