I tried to sit up but hesitated. It was because the clothes I was wearing were something I had no memory of.
Black. A form-fitting top and short bottoms. Belts, chains, and fabric of a texture I'd never seen before. I had certainly never worn clothes like this before I fell asleep.
My heart began to beat rapidly. Is this a dream? Or—

The voices of girls could be heard from somewhere.
Voices mixed with anger, panicked breathing. I wasn't the only one.
