Did someone say zombie movies?
Well, you may be right, Lisa - who knows?
My Mom always had a very strict "no scary movies" policy when we were kids - of course, we tried to argue about it, and when we were young adults, had to find out what we had missed.
But, now that I'm middle aged, I think she was brilliant
I noticed that my friends who had grown up watching scary movies tended to be more frightened of everyday things than those of us who hadn't.
For instance, when I drove cross-country by myself, several friends said they would be afraid to do that. And, an extreme case, when I led my officemates down a dark staircase to get out of our building, and had to both lead the way AND turn over my light source, because several of the MEN were afraid!
It could be that the two have nothing to do with each other, but I'm not sure that our subconscious mind always differentiates truth from fiction and sometimes we can be more influenced by fiction than we realize.
