Another really scary one could be 'My phone rang at 3 am. The caller ID said it was me.' It plays on the idea of the self being something other or unknown, and calls at that time are always spooky.
Here's another: 'The old mirror in the attic showed a face not my own. I smashed it, but the face still haunts me.' This is a classic type of two - sentence horror. It quickly sets a spooky scene with the strange face in the mirror and then adds a twist with the face still being a problem even after the mirror is broken.
One way to sentence horror stories is to build suspense gradually. Start with an ordinary setting or character and then introduce strange elements little by little. For example, you could begin by describing a normal day in a small town. Then mention a strange noise that no one can identify or a person who behaves oddly. Use vivid language to describe the uneasiness that starts to spread among the characters. This makes the readers feel on edge as they wonder what will happen next.
Some streaming platforms like Hulu or Amazon Prime Video might have it. You could check those. Also, sometimes it's available on the official website of the production company with a subscription.
