Screaming or howling

I have not had a nightmare in a long time. I watched <PERSON> for the first time yesterday... I was watching a movie with my parents and some other people. The movie was so horrifying that I had to close my eyes at parts. For example, in one part, there was a mother who lost her child and screams of terror came out of her. There was blood running down a path, the blood from her daughter, and it turned into dark ashes. At another point in the movie, it was like a war scene from Lord of the Rings. After the movie, some people laid down on the ground and the director of the movie asked who wanted their legs sawed off. It was apparently just for show and not real. A guy volunteered. He was overweight, had brown curly hair, and wore dark clothes. The director got a saw and started sawing through his leg. It looked pretty real to me. We were forced to watch this movie twice, and the second time, it became real... I was with <PERSON> and was popping popcorn. A black guy and some other guys came up to us. The black guy asked me if I wanted to "hang out" with him and of course I was hesitant so I said no, but for some reason eventually agreed. We started walking away and then he told me what we had to do. We had to sneak up on these guys and kill them before they would kill us. We were in a huge clothing warehouse and the guys were sitting on a window ledge. They saw us and came towards us. There was lots of fighting. At one point <PERSON> and I were throwing darts at each other(lol). Then sirens went off... Everybody ran away. It was me and a group of people left, consisting of the black guy, one girl, and a bunch of other guys. We did not have time to run back, so instead we ran forward. It was like a game and we had to get to the end. We ran towards a window that was facing a brick wall. It was night time so we could not see much except the reflection of us. The "creatures" were coming. I was so scared I closed my eyes. The black guy said, "do not close your eyes, look at my finger," for if I closed my eyes they could get me. He told me to look away and stand still and that way they will not see you. The "creatures" came up behind us, but they appeared as a copy of us. The girl turned around to see them. Big mistake. When she did that, even more appeared. She tried stabbing one of them but it was no use. They were surrounding us. They were about to attack... I woke up and it was 6 am. I was too frightened to go back to sleep because I did not want to go back to the dream. Everytime I closed my eyes I would see dead bodies and blood and scary creatures. So I wrote in my DJ and left the light on and finally went back to sleep.
