Well, without more context, it's difficult to tell the exact 'taily bone scary story'. It could be a story where a taily bone is found in an unexpected and spooky place, like in an old, abandoned house. And perhaps the bone has some sort of supernatural power that starts to cause strange and terrifying events to occur around it.
There was a derelict house on the outskirts of town. People said that the former owner used to make bone soup. One night, a group of curious teens decided to explore. They found a big pot of bone soup still on the stove. As they got closer, they heard strange whispers coming from the soup. The bones started to move and form a skeletal figure. Terrified, they ran out, and ever since, the legend of the bone - soup - haunted house has spread.
One possible theme could be death. The bones in the bone soup can represent the victims who have died, perhaps in a gruesome way. It gives a sense of finality and horror.
One bone chilling scary story is about the haunted house on the hill. People say that at midnight, you can see a ghostly figure in the window. No one has been able to stay in the house for more than an hour without running out in fear.
For me, the story of the SS Ourang Medan is the most bone - chilling. The ship sent out a distress call saying 'All officers including captain are dead lying in chartroom and bridge. Possibly whole crew dead'. Then, when another ship came to help, they found the crew all dead with horrified expressions on their faces. It's just so creepy.
Use vivid and detailed descriptions of the setting. For example, describe a dark, cold and damp cellar with a strange smell. Also, create suspenseful situations like a character hearing strange noises but not knowing what they are.
Some scary titles are 'Midnight's Shadow'. It creates a sense of fear as midnight is often associated with the unknown and things that go bump in the night. 'The Ghostly Gaze' is another one. It makes you wonder what kind of ghost is looking at you and what it might do. Also, 'The Abandoned Asylum' is a classic. Asylums are already creepy, and an abandoned one must be full of terrors.
There's the story of an old, derelict hospital. Urbexers found surgical rooms with blood still on the tables. They also noticed that the gurneys seemed to move slightly as if pushed by an invisible force. And there were always cold spots in certain areas, making it a truly spine - chilling exploration.
The idea of being alone in a forest at night can be very bone - chilling. The sounds of the forest become menacing, the trees seem to take on strange shapes in the dark, and there could be an unknown presence lurking. And if the character starts to get lost and realizes they are not alone, it becomes even scarier.
