The unlockable Door and the patient Pursuers

"I was in some old school building at night, hallways lit that weird greenish color, and I knew without being told that they were behind me, two or three of them, pale, walking fast but never quite running. Every time I looked back they were the same distance away no matter how hard I ran. I tried ducking into a classroom and the door wouldn't lock, the handle was just loose in my hand. hid under a desk that was somehow too small to hold me, listening to their shoes on the tile, slow, patient. One of them said my name, casual, like a friend would, and that was worse than any growl. Then I was outside on a street that looked like my aunt's neighborhood, running past houses with all the windows dark, trying doors, nobody home. My legs felt like they were full of wet sand. I remember wondering why I hadn't just gone home, like it was an option. Woke up with my hand pressed against my neck, heart pounding, not wanting to look at the window."
