Haunted

Nowadays, more and more people commit suicide, get lost, or have their body parts found. But the government does not know the reason for this. More and more people will be depressed at a younger age. A secret organization investigated what this was about. And they want to do all sorts of things against it. Sarah's mental state is also moving towards depression. Because she sees non-human figures that others don't.. I wonder what they are? What do they want from people? Why can't most people see them?
