Losing hair at the high School locker

"I was standing in front of my high school locker trying to unlock it with a set of house keys, but I kept running late for a bus I didn't even have a ticket for. I reached up to push a strand of hair behind my ear, and my hand came away with a massive, heavy clump of dark hair tangled between my fingers. Panicking, I ran into a dimly lit public restroom to look in the mirror. I gently ran my fingers through my hair again, but entire handfuls just kept sliding right off my scalp without any pain at all, leaving these smooth, cold patches on the top of my head. I tried desperately to stick the loose clumps back onto my hair before anyone walked in, but they kept slipping through my hands like wet straw. Suddenly the bathroom vanished and I was sitting on a bench in an empty train station in the rain, holding a paper bag overflowing with my own hair, this sickening, cold weight of absolute terror settled deep in my stomach."
