Dream of screaming, eyes

I was in a forest , which I recognised as it is local but it looked different. It was more swamp like , a bog even. I was walking through it looking for someone then I heard screaming , howls of agony , a man by the sounds of it. So I went further to investigate. When I saw two figures , a man huddled down on his knees , screaming in pain with blood seeping down his face. And the dark outline of a man , seemingly made out of darkness. He had his hand scraping away into this man`s head. Upon seeing me , he stabbed him in the head with what I think were claws , killing him. He dropped the body to the floor and stood and stared at me with dark red eyes. He opened his mouth and sharp , white teeth smirked at me. I ran , terrified but it was difficult as the ground all of a sudden had become marsh-like , flooded. As I ran I felt a something grab my leg and I fell down to see a pale hand clinging onto my leg from the murky water. I screamed and tried to escape , but all I could see was the dark figure slowly walking towards me.
