It would start with sirens. Not just because Silent Hill, because sirens mean one of my worst nightmares is about to show up.
Tornados. Whirling, shrieking cyclones of death rip through the area, destroying buildings, turning everything around me into shrapnel, stripping the very land itself down to a blasted, dark hellscape as they pass, sirens blaring. The sirens fade into the background as I am left alone, in dire need of shelter. Whenever I am outside, I constantly feel watched, yet totally alone, at the same time. When I get into a strong, windproof building, the wind still howls like screams and whispers outside, the sirens taunting me at the edge of my perception. I hear scuttling in the halls just ahead of me and right behind me, but I never see what's there. In the building is a tableau of all I hate about myself, every self loathing on display like a grotesque gallery. Once I am inside, I can't get out, for outside is nothing but tornados now, battering on the walls. All I can do is go deeper, to see more of my own failures, which get worse and worse as I go farther in, and the creatures I share my space with get closer and closer and still remain hidden.
When I get to the center of the building, I see my entire mind laid bare like a cadaver on a slab, and my friends finally make their appearance.
Spiders. Giant, scuttling, thin-legged spiders composed of the very essence of my worst and most hated memories, my most repressed urges and thoughts. As they close in, the building finally gives way to the winds, and is blown away, along with the ground, leaving me on a patch of ground floating above an abyss as the spiders continue towards me. Everything fades to black as the sirens blare.
