This quote reminds me of how sometimes you might be kind of nervous or uneasy at some sketchy place so you might act a little different or anxious. So you might walk a little faster or maybe decide to go where there's more people. The thing that causes that... is fear.
In the first few paragraphs of this article, it gives examples of people in sketchy situations where their gut told them one thing, but they did something else. In one of them, a women was done shopping and a man asked to help take in groceries. She felt that something wasn't right, but she didn't want to seem rude. So she let him help her later realizing that she let a rapist in her home.
In the t.v. show scream, a boy named Brandon James who was born with a deformed face and was made fun of it through school. So a surgical mask was made to support his face shape. (important later) One day there was a dance and he wanted to go with a certain girl but when another boy asked her to the dance instead. He was made fun of so much for being obsessed with this girl, he snapped and killed multiple students but was shot by police later. His legacy wanted revenge on the town and put his mask on and started killing friends of the special girl's daughter. My theme is on how fear can sometimes save your life, in this show, the main character is fueled by adrenaline when she is scared and always escapes when the killer is near.
