Watch Dr. Pimple Popper and you'll see my fears. That and itty bitty holes all over someone's body... you ever seen a frog with holes in its back while other frogs hop it's just... disturbing.
I personally don't find gore or dismemberment disturbing, but I have a specific fear when a woman who's all dainty, sweet, and soft-spoken gets dismembered or shredded or set on fire. I remember Akira freaking me out when Kaneda's girlfriend gets crushed like a zit and her eyes pop out. She didn't deserve that. She was literally the sweetest character in the entire movie.
I have a personal belief that those types of girls should never.... EVER die. They deserve all the hugs and chocolates and giant stuffed teddy bears in the world (yes I have a type, how'd you guess?), but when you do it out of nowhere it sorta reminds you that death don't discriminate. But I guess that's what happens when sweet girls like that hang around with criminals.
It scares me even more when it happens to ladies with glasses. Like in GTA V. There's a scene where you chase this chick down to the airport. You weren't going to kill her. You just wanted something from her. Even the character you play as was like "Just... chill", but she gets so scared she tries to run inside the jet while the turbines are still running and she gets shredded. Just blood starts spraying everywhere. All she wanted was to make her boss happy, who doesn't even love her, but she's obsessed with him. But again, it reinforces that no one's safe when working with these types of people.
Speaking of which, I remember Deadpool 2 freaking me out with the scene where the X-Force was getting killed one-by-one. Probably the most elaborate way to scare me. They've set the X-Force up like the Avengers through advertisement and was super meta about it. And then Shatterstar being incinerated by Helicopter blades and then Hazmat falling into a woodchipper.
Also woodchippers scare me. Getting your head run over by a car scares me. Yeh....
I will say, I will include stuff that scares me in my stories because why not?
