Visibility zero-zero

Murkiness, miasma stifling me
Visibility is zero-zero impossible to see
Such a smokiness of smog silhouetting shapes
Oh how I hate the fog, dellusional darkened drapes
A calignosity of gloom
On this dreadful dismal eventide
Duskiness of doom
Absolutely anyone could hide
So I panic when I run feeling so uncomfortable
With my heart beating out my chest 
This opaqueness is intolerable
Cimmerian shade
Crepuscule of black
Vespers amidst twighlight
Giving me a heart attack
Sweat saturating me though I am chilled 
Outside in the open air my uneasiness unwilled
Running for the radiance of yon dim street light
Yet any lantern is my salvation and a welcome sight
I am relaxed and relieved now I am away from the park
Never ever again shall I be alone in the dark
