When I was a kid, a strange man tried to grab my arm while I was waiting for my parents outside a supermarket. I screamed really loud and he let go. He quickly ran away when people started looking. It was terrifying as I was so young and defenseless.
The element of being unprepared is quite common. People are usually just going about their normal day, not expecting any danger. For instance, you might be walking home from work or school, not thinking that someone could be plotting to kidnap you. And then there's the quick decision - making that has to happen, like whether to run, scream or try to find help immediately.
One possible reason could be that the kidnapper is a sadistic person who gets some sort of twisted pleasure from hearing horror stories. Maybe it's part of their sick game or way to terrify the girl further.
She could recall the horror stories she has heard before. Maybe she has read books or watched movies with horror elements. She can use those memories to retell stories. If she was a fan of horror genre, she would have a reservoir of ideas to pull from.
One time, I was walking home from school alone. A van pulled up beside me and the driver asked if I wanted a ride. I said no but he kept insisting. I started running and hid in a nearby store until he drove away. It was terrifying.
Often, the kidnapped author will start to draw on their creative thinking. They may try to create a story in their head to either escape or at least understand the kidnapper's motives. They could start observing their surroundings carefully, looking for any weaknesses in the kidnapper's setup, like a loose board in the floor or a faulty lock on the door. They might also try to befriend the kidnapper, using their charm and intelligence to gain an advantage.
One common plot twist is that the kidnapped author is actually the mastermind behind the horror. They might be using their own 'kidnapping' as a way to create the most terrifying story ever. Another could be that the kidnapper is a deranged fan who wants the author to write a specific ending for a series. Or perhaps the place where the author is held captive is a portal to a more sinister, otherworldly realm, and the kidnapper is trying to force the author to write about it.
One real kidnapped story is that of Elizabeth Smart. She was abducted from her home in Utah in 2002. She was held captive for nine months. Her captors were a religious fanatic and his wife. Eventually, she was rescued when she was recognized in public. It was a terrifying ordeal for her and her family.
A girl in my neighborhood was almost kidnapped. She was walking her dog in the evening. A woman came up to her and started asking her a lot of questions about where she lived and if she was alone. Then the woman grabbed her arm. The girl's dog started barking loudly and she managed to break free and run home. It was so scary that she didn't go out alone for a long time.
