Sure, 'creepy yarn' can be used instead of horror story. It gives the idea of a story that makes you feel uneasy or gives you the creeps.
A 'macabre story' is also another way to say horror story. Macabre refers to things that are disturbing and often associated with death or the grotesque, which are typical elements in horror stories. For example, stories about haunted houses or vampires can be considered macabre. These types of stories often play on our fears of the unknown, the afterlife, and things that go bump in the night.
Here's another horror hot story. There was a derelict carnival ground. A journalist went there to do a story on the abandoned place. As she walked among the rusted rides, she felt like she was being watched. When she entered the funhouse, the mirrors distorted her reflection in a very creepy way. Then, she heard a voice whispering her name. She turned around and saw a clown - like figure in the corner. She ran out of the carnival ground, her heart pounding with fear.
Another word might be 'technological fantasy'. Science fiction often involves fantasies based on technology. It takes real - world scientific concepts and extrapolates them into wild and wonderful fictional scenarios. This term captures that aspect of science fiction where technology plays a huge role in creating the fictional elements.
A common alternative word for a horror story is 'scary tale'.
Dirge. A dirge is a slow, sad song or poem, and it can also be used to describe a story that has a very mournful tone. It's not as commonly used as some other words for a sad story.
Amatory account. 'Amatory' is related to love or sexual love in a more archaic sense. So an amatory account can be a story about love, perhaps with a more old - fashioned or literary feel.
The word 'anecdote' can also be considered. An anecdote is a short and interesting or amusing story about a real incident or person. It's a small part of a true story, but still represents a real - life situation.
Phantom narrative.
Success stories are often about how someone overcame difficulties and reached their goals. 'Accomplishment anecdote' can be another term. An anecdote is a short interesting story, and when combined with accomplishment, it can convey the same meaning as a success story.
