In Nigeria, it's often believed that only evil people or fraudulent people are awake by 1-3am, Mostly, the latter.
I love to sleep. I sleep alot. I don't joke with my night sleep.
Food? I can't eat in the midnight. It's waste of food because if I sleep back, I'd wake up hungry again.
Yeah, there are superstition and supernatural beliefs around the world that associates those hours often with evil. It's why I personally find that sometimes there are days when waking up in such hours can be scary.
