When the Ghost Possessing you is a Horny Murderous Speedster.

Alice is a fangirl. She had started obsessing over Reverse Flash lately and one day while walking to the store, her earbuds buzzed with static. She didn't think of anything until she crossed the road. She suddenly felt the urge to run and did so. Oc is not a runner because her legs usually hurt. She had felt like she was flying when she was running. Then she hears a voice in her head. A male voice. One that vibrates like a speedsters.
