Screaming or howling

I dreamed that outside my room which is on the first floor, everything was dark, and you had a strong feeling of something watching you, almost like ghosts creeping around the hallway with malicious intents. There were people with me, but I do not remember who, and I do not remember our conversations. I walk down the stairs and come to the floor below. The feeling of being watched is stronger and grows more toward the feeling of being chased. The air gets more dense, the light in this hallway is slightly more of a red tone instead of the nightly dark blue tone. I start seeing corpses and carcasses, bloody rib-cages ripped open with the limbs torn off, lying around. A guy I am with says we should not go deeper. We go deeper anyways, down the next flight of stairs. As we go deeper, the place becomes more horrifying. More violent carcasses, red hellish lighting, and you can almost see and feel the malicious spirits move around in the air, gazing at us. We start hearing the screams of people getting murdered. Bones and carcasses still lay scattered around, like some messy slaughterhouse dealing with humans, except the place looked more and more like a cavern and was too dark to see far. A guy I am with says: "We should stop here. If we go any further, the ones with four eyes will appear, and any further than that, they will tear our limbs off." I am curious what those four-eyed things would be, so I want to keep going, before I come to the sudden realization that the corpses, carcasses and bodyparts were not just brought here for decoration; something might do that to us. "Alright let us get out of here." I say, and we rush up the staircases, panicking more and more until we get back into my room and close the door.
