What would YOU do if you were trapped inside the asylum alone?
The second film showed that you can survive in there alone if you know what you're doing. How long would it take you to stop being scared? Weeks? Months? Years? What would you be doing? Would you try to unlock the mysteries? Would you be able to keep your sanity? How long would you keep looking for a natural, physical way out until you give up completely?
I think I would take a LONG time until I stopped being scared, if ever. However, once I became numb to the demonic faces and constant real life jump scares, I would make a sort of "professional career" out of it. I would try to get as much as I need to make a detailed map, and I would constantly take notes about each and every inconsistency and pattern that arises. I want to know that place like the back of my hand, and every ghost inside.
