When I was a (younger) child, I use to go the movies on some Saturdays. They would have 2 features for a quarter or so. Usually at least one of the movies was a horror movie (probably what they call a B movie now). These movies were not as graphic as they are now-a-days. But they were scary to me. Usually all of the blood was via innuendo, they would show a knife or whatever maybe swinging down but go to the face of the murderer / monster when it landed. They would usually have fog with scary sounds in the night.
I no longer go to horror movies. There are too scary for a delicate creature such as myself.
This morning on the dog walk, it was a very foggy environment. And of course, I keep hearing creepy sounds. It was probably the wind or the raindrops falling plus I had my trusty (fraidy cat) dog; but I would look for the monsters or villains in the mist! Never goto horror movies when you are young (hopefully this warning is not too late for you)!
