Screaming or howling

I was walking around my neighborhood at twilight. The sky was starting to get dark, with streaks of orange here and there. For some reason, I decided to turn left down the street toward my friend's house. Suddenly, I saw a huge shadow on the ground, moving really quickly. It turned left just as I was about to. It was pitch black, and very long. Kind of like a giant snake in form. It also made this weird sound like scales being rubbed up on the ground while it moved past me. It all happened very quickly, and then it was gone. I stopped in my tracks. I knew what it was. It was the face stealer. I had seen it in previous dreams, and this time, it somehow triggered lucidity. As soon as I got lucid, I heard the sound of its scales moving closer, until it just stopped. In the next instant, the shadow creature was in my face. Its head was massive, I could probably put my arms around it if I tried, which I did not. It was not a shadow this time though. I could barely see its body extending infinitely, with dark green and blue scales like that of a reptile. I realized it did not look like a snake - more like a dragon without legs. (okay maybe that is a snake already lol). The strangest thing was that its face seemed to change appearance very rapidly, like alternating between channels. I did not recognize any of the faces though, but everytime it shifted, its eyes always looked straight at me. I had been waiting to confront this monster for quite some time now, as it has haunted me a lot in the past. Luckily, I was lucid enough to know what to do. The face stealer was a made-up version of something I saw on TV. They are different in appearance, but they had the same motive - they would steal your face once you showed any emotion. So I stayed still and let my face go slack. It was really hard because the creature was so scary and disturbing. Finally, I thought of an idea! But too late, it must have seen the surprise on my face. I suddenly felt my face contracting slowly. It was not painful, but I could feel it happening. A few seconds later, it stopped. I saw my face depicted on the face stealer's head. It was smiling eerily at me, with those crazy eyes like it wants to kill me. It was so weird seeing my face like that, and so huge. Then I realized I could not talk. I tried to scream but nothing happened. I could see though. I put my hands to my face, and there was not anything on it. Literally. I poked the area where my eyes should have been, only smooth skin there. I apparently also did not have a nose, though I could breathe just fine. I did not have ears, nor a mouth. I had lost my whole face. In a strike of perfect luck and timing, an idea popped into my lucid mind. I thought, since this was my dream, surely I could do something! I decided to be the face stealer this time. I closed my eyes (well, not really because I did not have them, I simply chose not to see). Then I imagined the monster's face (my face) slowly contracting while I absorbed its features. I could hear the monster grunting as this was happening, until finally I only heard silence. I opened my eyes, and saw that the monster did not have my face anymore. No rapid shifting of faces either. It was just...a ginormous lump of coal with a scaly body. It was not moving either. I felt my face with my hands, and I could feel my mouth, nose, eyes, and ears - back to normal. I flew away and never looked down. I went on to complete some goals I have been waiting to do, before I finally lost lucidity and woke up.
