Screaming or howling

Once again, I had multiple dreams. The first dream was during the night. The location was on some sort of colony ship in space. Most of the people in it had evacuated due to something happening. I am not sure what it was, but it was probably due to mutated killer animals running loose and killing people. I remember I was hiding with 2 other people. We were underneath the floor in some sort of maintenance room. One man was saying something along the lines of " If we survive this, this would make such a great Sci-Fi movie.". Of course, after saying that, a mutated tiger monster thing reached down from somewhere and ate him almost whole. Using that as a distraction, I was able to get away. Another dream, I was sen to the store to get a few things. Arriving at what I thought was Kroger, I went up to this main counter thing, and had to get a number. Once a number was called, we could go in. My number was 300. O_o Looking around, I could see that this place was far more than a grocery store. Connected to it was also like some sort of casino type place for some reason. I remember after talking to a few people about pretty much boring stuff, or asking about how to just get some stupid groceries, I gave up, gave my ticket to some random passerby, and left. My final dream was more along the lines of a nightmare. I recall seeing some little kid come out of a dark room crying and being extremely frightened. I am not sure where this was, but I decided to face what was in there. In the room, now with the lights on, were a few mirrors, and a door leading in, and another leading out. I did not see what the deal was, so I turned out the lights. Standing there for a few seconds, nothing happened. But turning around, I could have sworn I saw a face in my peripheral vision. Startled, I quickly turned toward it, seeing the mirror that was now dimly glowing. The figures became more clear, they were like very angry souls. I attempted to flee, but it was like my whole body was paralyzed, I could not even yell for help. Then things got weird. If I recall correctly, it was like looking into a mirror reflecting a mirror, seeing infinitely and filling my whole vision. I could hear the screaming of the shadowy people getting loud, At some point, I think I managed to make it to the door, when I woke up. At least I thought I did. I believe I had a few false awakenings before I finally woke up.
