I punch the roof of the elevator mainly to make noise and maybe scare whatever it is thats up there away. I open up the shaft, take a hold of it and use it to protect myself while i find a way to an opening and become free.

Youre in your room. All of a sudden a strong wind starts, so you close the window. All of a sudden your door shuts close, making an irregular amount of noise, almost like a scream. The force of the door is so massive the walls shook a little, and little cracks are now slowly appearing, almost as if the walls are made of paper and someone is taking a knife and cutting them up. The walls now collapse and while everything in your room is still there, you are surrounded by darkness. The window slowly opens up, offering a desperate escape attempt - one that will get you killed. You realize that the darkness is closing it, and that strange black, shiny figures are crawling with the darkness, almost as if the light is harmful to them. You only have a lamp, your computer, a cordless phone, and your bed (hint, sheets). However, the bed is dangerously close to the dark, and it is still closing in on you.
Good luck.
