Sleep Tight

The book delves into unsettling mental states, and I'm curious whether the author drew from real cases or created a completely fictional mind.

The tension seemed to dip for a bit, but then picked up again. I'm wondering if that was a deliberate choice to build suspense or just a natural part of the story.

Switching viewpoints added layers to the mystery, but I wonder whether this was planned from the start or evolved during the writing process.
