She is in a cave. The darkness had consumed Equestria, only a hoof full of ponies remain. She is one of the few survivors. The only safe place is the Everfree forest. And that's saying something. Now, she is stuck, all alone, in a cave, deep in the Everfree forest, trying to survive. But, how can you, when, every little noise you hear, every drop of water, every rustle of leaves, every hoot of an owl, makes you jump, and you slowly lose your sanity.

My poor attempt at a horror story. Don't know weather it should be mature or teen. But, just to be safe, it's rated mature. It's also late, so, sorry.
Happy Nightmare Night!
