This is a psychological horror story. And it is a story of great love. It is dreadful that the demon-like creature should appear on Granny's face. Lovely, weak Granny. So the reader must wonder, is this the hallucination? Or is a demon torturing the protagonist? Most readers will believe that the protagonist is suffering from a psychological break. Of course, only the author (you) knows for sure what the truth is.
Thank you for sharing the short story with the Ink Well community. And thank you for engaging with your fellow authors.
