Sleeping in the Dark

I prefer to sleep in a room that's as dark as possible. This preference existed even before I learned about the benefits of sleeping in darkness, like improved melatonin production.

Bright light can be like noise—a disturbance to peaceful sleep.

As a child, I was scared of ghosts, yet I still preferred sleeping in the dark. This wasn't the case for others, according to stories I've heard about children who fear darkness and need lights on. Some can manage with just a reading lamp, but sleeping in a completely dark room is out of the question for them.

It's probably just a matter of preference—not a big deal—until you need to sleep with someone who has opposite sleeping preferences.

I can make exceptions and compromise by creating darkness for myself, perhaps by using a piece of cloth or a sleep mask if one's available. Though sometimes when I wake up, the sleep mask has usually slipped away from my eyes.
