Almost Surely Dead

The mood of the story really pulled me in, but I wonder if it was based on personal experiences or just a vivid imagination. How did the author craft such a chilling tone?

The story seemed to peel back layers of the protagonist's self, making me question what makes someone truly themselves. Was this intentional or just my interpretation?

The story jumps between timelines smoothly, which kept me guessing. I'm curious whether this was mapped out beforehand or evolved during writing.
