It sounds like you're looking for the fourth chapter of a horror story! Since there are many stories with a "Chapter 4," I've summarized a few popular ones below.
If you were following a specific story here or on a site like Wattpad, let me know a few more details so I can find the exact one for you.
1. "Whispering Woods" (Online/Wattpad Series)
In Chapter 4: Marked, the protagonist, Sydney, has a terrifying dream where she finds herself back in her childhood home.
* The Twist: She sees a tall, shadowed figure in a mirror who whispers that she is "marked."
* The Discovery: When she wakes up, she finds muddy footprints in her room that aren't hers and an old, burnt photograph with a chilling message: "One must pay so the rest may live."
2. "A Shady Plot" (Classic/NCERT Literature)
In many literature curriculums, Chapter 4 features a story called A Shady Plot by Elsie Brown.
* The Plot: A writer who struggles to come up with ghost stories is visited by a real ghost named Helen.
* The Conflict: Helen explains that ghosts are on "strike" because people use Ouija boards too much, which makes the ghosts' jobs exhausting. She tells the writer he must get his friends to stop using them if he wants any more ideas.
3. "American Horror Story: Roanoke" (TV Series)
If you are watching the show, Chapter 4 is where the backstory of the "Lost Colony" is revealed.
* Key Event: The character Cricket learns about the "Old Magic" and the witch Scáthach (played by Lady Gaga).
* The Ending: It ends brutally with the "Butcher" attacking the house and sacrificing one of the main supporting characters in front of the others.
Which one were you looking for? If you'd like, I can:
* Write a custom Chapter 4 for a story we start together.
* Find a summary for a different book or series (just tell me the title!).
* Continue a story you've already started telling me.
