Things to Run Away From Really Fast

I'm running up an underground staircase. I had the route planned out ahead of time, parkour sequences that he won't be able to duplicate. I've run through the attic of a school and into this place, a spiralling staircase with nothing but a thirty-story fall down the center.

I get to level ground, and something feels off. I look at my hand. It's clawed, and pale-white, and moving on its own. I watch with sick fascination as the fingers move in impossible patterns, until I tear my gaze deliberately away, trying not to get more freaked out.

When I look behind me, nothing is following. I look down the staircase and wonder what would happen if I -

I jump.

I feel the sick thrill of falling for a few seconds, before I reach out and catch myself in a web of orange and yellow, meters from the stone floor. I float in mid-air, close my eyes in contentment, and wake up.
