Why Do Some People Prefer Darkness Over Light?

Some people like the dark because it feels safer and calmer. Imagine you're in a room, and there's just a tiny light on, maybe from your phone or a nightlight. That little bit of light can feel like it’s watching you or making everything too obvious. In the dark, everything is quiet, and things aren’t so clear, which means nothing can jump out at you suddenly.

Other people prefer light because it helps them see and think better. Like when you're reading a book in bed, if it's too dark, you might squint or even fall asleep while trying to read. Light makes everything easier to understand and feel more familiar.
