有士兵坚称他们在夜间站岗时，尤其是午夜到凌晨4点之间，通过夜视镜看到了奇怪的光，还听到了类似爬动的声音。

Soldiers said they could see weird lights through night-vision goggles and hear odd creepy sounds at night, especially from midnight till 4 am.

但我还是需要考虑些更积极的策略，尤其是在凌晨一点到五点之间。因为在这段时间内身体和精神上都很疲惫。

I may need some better strategies for making it through the 1am - 5am cycle though, since drowsiness peaks during this period, and physical energy is low as well.

因为每天我醒的时间比以前长的多，所以日子感觉过的很慢。尤其是在半夜和凌晨。

I'm awake many more hours each day, so the days seem to pass more slowly, mainly due to being up all night.
