Perhaps Sheetal Singh is in a hospital at night. All the lights go out except for a faint red glow at the end of the corridor. She hears the sound of a gurney being pushed, but there's no one in sight. As she follows the sound, she enters a room filled with old medical equipment that starts to move on its own, and she realizes she's not alone in this haunted hospital.
Maybe being trapped in a dark cellar with some unknown and terrifying creature that is slowly approaching her. The only sound she can hear is its heavy breathing and the scraping of its claws on the stone floor.
For Sheetal Singh, it could be finding herself in a room full of mirrors where she sees distorted versions of herself in each mirror. And then, as she tries to break free from the room, the mirrors start to crack one by one, and from the cracks, a dark mist seeps out, slowly engulfing her.
Sheetal Singh was a young woman who loved to explore. One night, she went into the forest. Sheetal heard whispers all around her. As she walked deeper, she came across an ancient tree. There was a strange symbol carved on it. Sheetal touched it and immediately felt a chill. Then, she saw a pair of glowing eyes in the bushes. It was a wild, menacing creature. Sheetal started running, but the creature was fast. Sheetal found a small cave and hid inside until dawn, when the creature finally disappeared.
Probably being trapped in a place full of supernatural entities that he can't fight with his normal skills. For example, if he's in a haunted mansion and there are ghosts that can pass through walls and mess with his mind, he'd be completely out of his element. There's no training in the FBI that can prepare him for that.
Maybe a secret cult in a town. Everyone in town knows about it but won't talk. They just say 'none of your damn business' when outsiders ask. One outsider starts to dig deeper. He notices strange symbols painted on some houses at night. Then people start acting really weird around him. He's followed everywhere he goes. One night, he wakes up to find a group of people in hoods standing around his bed, just staring at him without saying a word. That's pretty scary.
One possible plot could be that Prince Singh inherits a cursed kingdom. Every night, as the moon rises, the dead from the graveyards around the kingdom rise and start to march towards the palace. Prince Singh has to find a way to break the curse to save his people and himself from this nightly horror.
The unknown origin. If you can't remember how you got a hickey and it starts to have strange symptoms, like changing color or shape, it's really scary. It makes you wonder what kind of force or entity caused it.
The scariest element could be the loss of control. Just like in the case where a person's long nails start to act on their own, moving without the person's will. It makes one feel powerless against this strange and unnatural phenomenon.
The scariest thing could be the loss of control. As the '69 countdown' proceeds, things start to go wrong. You can't stop it. You might be trapped in a room where the temperature is dropping rapidly, and strange symbols are appearing on the walls. And when it hits zero, you don't know what horror awaits, whether it's being dragged into a dark void or something even worse.
Perhaps the scariest part is when the saffron, which is usually associated with beauty and luxury, turns into a source of danger. Like in a story where saffron powder is used in a voodoo - like ritual against someone. The person starts to have hallucinations and feel a strange presence every time they are near saffron, which was once a normal and pleasant thing in their life.
The sudden movement of the chopsticks on their own. It goes against the normal use of chopsticks and is very unexpected, like in a story where a person is calmly eating and then the chopsticks start wriggling in their hands.
The scariest part could be when the donuts start to come alive. Just imagine you're sitting there with a plate of donuts, and suddenly they start to move and show signs of life. It's a total violation of what you expect from a donut, and it would be really terrifying.
