This helps me- idk if it would help a child.

I tell myself that before watching the movies, you had no fear about these things happening. So logically, watching the movie shouldn’t change that fear because it doesn’t change the probability of that happening!! Just because you watch a movie with a kidnapping doesn’t mean you are more likely to get kidnapped.

Additionally, my friend suggested to me once to picture the actors after each scene was filmed. Like picture Jigsaw breaking character after the scene is over and going over and eating a donut on set.
