Philip K. Dick - The Hanging Stanger
A hanging body can be more than just a shocking sight

Ed Loyce lives a happy and normal life is a happy and normal small town in mid America. But today something strange happens. In the late evening, on his way to work at his TV sales and repair shop he passes the tiny one block park in the middle of town and sees something hanging from the only lamp post, something big, almost like a body. Of course it must be something else, probably an ad of some sort or a joke. Not able to discern exactly what it is in the dusk, he parks and walks toward it. It is a body, a human body, a very dead human body of someone he has never seen before. But no one else in town seems to notice it at all. The strangeness and horror grow and expand as he slowly understands why this body was put there.
