I wake up after yet another dip into the endless darkness. There's a lot of white around and the light is blinding me until my eyes adjust. I sit up and look around. Then, suddenly, a gasp from the side takes my attention. I look over and see one pony, the unicorn from before. Behind her, black fills out the windows. Darkness has come. It must be night, yet I feel more awake than ever. As I try to ask her what's going on, all that results is a meaningless blurb, but it's something. She races to my side. I finally understand. I'm back. No more time to sleep.
