Overgrown Mansion

Lost in the woods at night you spot a suprising sight, an old mansion now overgrown by enchroaching foliage. Deciding it would be a good place to shelter you make the mistake of entering the front door. As soon as you do some kind of thick vines snap down blocking the door. You are now in complete darkness. Fortunately, the phone in your pocket has a whole 10% charge left on it.
