A Stain on Glass: a Psychological Horror of Reflection, Identity, and the Thing That Watches Back

There are some stains that never wash away.Some marks are not left on glass — but on the mind.A Stain on Glass is a slow-burning psychological horror about obsession, fractured identity, and the terror of being observed by something that knows you intimately — not as a person, but as a pattern to be studied, altered, and replaced.The story explores the quiet unraveling of reality when reflections stop behaving as they should, when memory becomes unreliable, and when the familiar begins to feel subtly, catastrophically wrong. What starts as unease turns into fixation. What seems imagined becomes impossible to deny.This is not a story of monsters that leap from the dark.It is horror born from recognition — the dread of realizing that something has learned how to be you.Unsettling, atmospheric, and deeply claustrophobic, A Stain on Glass is for readers who crave intelligent horror that lingers long after the final page. A meditation on identity, surveillance, and the fragile boundary between self and imitation, it leaves one question echoing in the silence:If the reflection remembers everything… what happens when it decides you are no longer necessary?
