One Up Seeker

I haven't had a nightmare in I don't know how long, but I had one last night so I figured I'd share it with y'all considering they're very rare for me.

1. I'm laying in a bed, on my side. As I awaken slightly I look around me and see that I am inside of a large classroom. The lights are off in this classroom and it is rather large in size. I can see that the floor is made of tiles, and at the front of the room I see an extremely large dry erase board, the kind that teachers use. All the way across the classroom, diagonally from me, is the classroom door. There is a window on the door and through it I can see lights on outside in the hallway. I look directly to my left and see that someone is sleeping in another bed directly adjacent to mine. I have no idea who it is, yet I don't really care either. Suddenly I hear a voice in the distance. The voice sounds kind of far considering it has an ambient tone to it, but it doesn't seem too too far away. Even so though, the voice is yelling. I feel like I know who the voice belongs to, but I am not sure.
"Cory wake up! Wake up now!" it yells. I've no idea where it is coming from, maybe somewhere off behind me? Anyhow, seconds later a being appears about a foot in front of me, just standing at the side of my bed staring into my eyes. I am frightened to say the least, but I cannot look away. The figure is wearing an all black robe, and its face is just pure black with the exception of two glowing red eyes. At this point my heart is pounding in fear, and the voice is still screaming for me to wake up right now. A few moments later I awake in the actual waking world. The being is now standing on the right side of my bed, still staring at me from the exact same spot. This goes on for what seems to be about 15 to 20 seconds, and I am terrified. I still cannot look away even though I am completely scared out of my mind. After those 15 to 20 seconds the being suddenly vanishes. I don't remember if it walked away or just straight up vanished.
Even after it left I felt some presence in my room, and I still felt a fear that I have not felt in years. I have no idea if it was real or all in my head, or even if it was a ghost or something else, but holy shit it felt real, and I haven't seen anything paranormal in a long, long time.
