You're walking in a dark alleyway at night, enjoying the lack of chaos that normally reigns in your city. You just bask in the loneliness for a good while, the silence of the street enveloping you in its comfortable embrace, until the tranquility is shattered by more footsteps. You instinctively glance around, trying to find the source of the noise, but see nothing. Suddenly, though, you spot the shadow of a skeleton, but it has to be your mind playing tricks on you.
