The Hurt Man

Who was the strange, injured man who showed up in a child’s front yard at random one day… And where did he go?
Here is a preview of the story.
“The weird things started happening when I was about 4 or 5. I was playing outside of one of my mom’s friend’s house. It was in the middle of the afternoon there were quite a bit of people inside celebrating someone’s birthday. I do not really remember who all of them are where either family or friends of my mom. Anyway, I am playing outside by this old, abandoned trailer in the back yard, and I see a man in a white tank top and blue jeans with his hands on his head bleeding awfully bad, and he appeared to be missing part of his head on top. He was screaming for help over and over. He looked very real. I was terrified and ran to get him help.”
