Screaming or howling

This is a nightmare I had a few nights ago. I was holding a young girl, an infant, in my arms. I was inside a building when a man pushed me into a room, slammed the door, and locked it. Inside, I saw a woman cowering in a corner, sobbing so violently she was shaking. I heard something being released through small rifts in the floor, and I felt suffocated. I was in a gas chamber. (Just to let you know, I was 20 ish in the dream. Six years older than I am now) I held the baby against my chest and fell to my knees, not wanting this baby to die. She cried and cried until I shushed her, calming her. They opened the door and took her from me, and I heard her screaming. The other woman lay dead before me. I stared in horror at the corpse before screaming for them to give her back to me. The baby, that is. The man from before laughed and kicked me hard in the abdomen, causing me to fall backwards. From this point on, it was like I was outside my body, watching the proceedings from afar. I saw him laugh as a woman ran up, a large wooden beam in her hands. She drove it through my stomach, and I heard a myself cry out, blood trickling from my mouth. She pulled it out of me, making blood spill EVERYWHERE. She drove it in again...and again.and again. I was begging for death. She laughed, torturing me until there was so much blood around me I thought I had to be completely drained. I saw her drive the stake into my heart, and, hearing myself softly grunt, I watched my body slump forward. dead. In the background, I heard a child crying until silence came and I woke up. Note: This is the first time I have ever seen myself die in a dream.
