Screaming or howling

It begins with me climbing over a short barbed wire fence. Within the fence is a single Sheep, And in a near by similar fenced in location is a Hog. The ground is Cracked, and grayish tan. Behind me it slopes up and disappears into the sky, as if we are on the side of a step, dead hill. There is no food nor water any where for the animals. Above the sky is a dingy, almost sickly green. The sheep is scared, and burnt along it is right side. The wounds are fresh, and barely scabbed over. However the sheep is very large, and aggressive. A voice from behind me let us me know it will not let me treat it, I am not it is <PERSON>. But I need it. I need it is meat, milk, and wool. else I will die. As I approach is charges at me, and I refuse to move. It changes direction and almost collides with the barbed wire. I remove my self from the pen. I cannot have it hurting it'self more. It has suffered enough. The voice then leads me away from the pens, we travel down the slope, along a dusty trail. Eventually a river comes into view. However as we continue down it smoke fills the air. The world grows darker and darker until we reach the river and we cannot see more that 100ft in front of our faces. The river is also lined with 12 ft tall wooden posts from which barbed wire is strung hap haphazardly. Similar to the pens we had left. The voice passes to in-front of me. He is a general from the war that caused this, he is my friend. He explains that this fence was made to keep the enemy from crossing over the river. He opens a large gate, and leads me to the side of the river. The river is a sickly brown- green, like the water is dead. Destroyed and sunken ships lie just beneath the surface. Directly in front of me is an old weathered pier, with a matching wooden overhang for rain. The front posts are gone, and a half sunken ship lies there holding it up. My friend points to a still intact ship across the river. He says there are leads and food for the animals on it. When I turn my head for a second, he leaves to attempt to walk across the ships like stepping stones. I turn back to see him and he has disappeared from sight And I know he has drowned. Rain begins to fall and I try to cross the river my self. I make it to the first ship that has holds up the pier. I step on it and the ship gives way. I can hear the voices of my family scream as both I, the ship, and the pier fall into the dead river. I try desperately to swim upwards, and I almost breech the surface, before I wake up. I am no stranger to messed up dreams, I have even had apocalyptic dreams but it is the first time I have had one this messed up. Just felt like sharing it.
