If you notice a co-worker is "disappearing" and the world insists he never existed...
If you see two completely contradictory handwritings, they both come from yourself yesterday...
If you are trapped in a building enveloped by strange singing, and any downward movement is equal to death...
If you smell a crazy aroma and see a chef pushing a food cart smiling at you, and you just feel bottomless hunger and start to swallow everything in front of you...
If you find a walking skeleton in the dark, and the frequency of your walking is gradually coinciding with its pace...
If you look up and see a rusty chain hanging in front of you, and you already feel an invisible weight on your neck...
Well, you have entered my world.

Understand the laws of ghosts!
Ghosts cannot be killed!
Only ghosts... Can deal with ghosts!
Remember them and you may... Live a few more days.
