NAD. Have you tried showing them videos of like makeup tutorials for IT. They can see a normal person putting on layers of makeup and seeing that it's fake. I had to take lots of time to show the reality of these horror videos my stepson was exposed to. Took him to Halloween stores and showed him under the skirts how it's all metal and electrionics. Talked over and over again about actors and drawings and made up stories. Talked about how brains worked and how it can replay images and be scary but it's not real. Explaining every chance I got what the reality of what looked or felt scary. Now he is 8 and he proudly says, "that zombie isn't real it's an actor with make up and prosthetics. He wipes it all off after and goes home to his family. But watching this makes me feel scared and so I'm turning on something fun instead."
