The head in a box obviously has resonances with the brain-in-a-jar trope of classic science fiction (and the head-in-a-jar parody of Futurama). There’s a lot of tension between autonomy and lack thereof when you’re a head in a jar (or a box). You can’t move on your own, you’re entirely dependent on outside technology and outside caretakers for your existence, but at the same time you’re free from a lot of mundane concerns: you can eat whatever you want, nobody’s going to ask you to make your bed or take out the trash, etc.

I started this story with the premise, “What would a ghost be afraid of?” The Neverman came right out of that. Incomprehensible forces are always scarier than ones we can define, so I’d rather let the reader decide for herself what the Neverman might represent. But I will say that a lot of what the Neverman is came from my subconscious fears, and so there may be something to your theory of nihilism. As a general life philosophy, I find nihilism lazy and myopic. To me, it reflects a failure of imagination.

A couple of years ago, I was listening to a lot of horror podcasts/radio dramas and true crime stories. “Tragically Murdered Little Girl” was a running plot element, and it grossed me out to no end. Whoever it was that said that the death of a beautiful woman was the most tragic, poetic thing didn’t account for the modern fixation on little dead girls. Dead kids are shorthand for “ultra-tragic” but they’re also dead children. They existed for themselves, they were complicated beings who had desires and bad days and relationships. Why shouldn’t those girls get their own stories?

Long ago, I ran across an article online about the summer getaways post-WWII, where disfigured veterans went. There was a line in the article that said something like how these getaways would be the only time the veterans felt the sun on their skin, because they would be allowed to remove their masks that they otherwise had to wear when in public. The article went on to talk about the artists that made these masks for the soldiers. I think I found more research on this as well, one article that highlighted a specific artist. And I thought what a beautiful image that was.
