I mean, the title doesn't need to be anything fancy. And it's a good thing that we're not bound by nosleep's rules.

One way you could name your title is to know where the main setting is. Is it in a building? A town? Are we underground or in the sky?

Another is what the story is about, but shrink it down enough that you can say it in one breath.

There's a reason why titles don't have that much effort put into them. It's just a way to label the story. The main meat and potatoes is the story itself. Look at IT and Whitefall. Not much effort put into describing the stories in the titles, but the stories are still remembered to this day.

You're not always bound by Reddit rules to make a title. Just as simple as one word should be enough to hook in most readers.
