Analysis of Psych!

Around me, it gets colder
I jump, look around my shoulder
Surrounded by an army of demons,
Some gruesome, some beastly
Do my eyes deceive me?

Fire! Fire!
They growl, flame blowing
An inferno quickly growing
Run!
Chased by monsters
The yells of imposters
Looking each and every way, I try to escape
Stumbling, trembling, running like an ape
In the distance, a fire exit
Away from the raging tempest
"What luck!", I exclaimed.

Fake!
A brick door
Just a drawing, nothing more
A deceitful illusion
Wait... what's this protrusion?
A cancer forming in my brain!
My throat throttled by an invisible chain
I struggle, drowning
Froth oozing, blood gargling
My body freezes from my head to my toes
Mustn't let... my eyes... close...

Sh... Hush...
Pitch black
No longer under attack
But I hear nearby murmurs
Perhaps in my brain, in the corners
I try to eavesdrop on what they are saying
Are they spying or innocently playing?
They're collecting intelligence, a suspicious act
Their theories and concepts seem awfully abstract
Sh! Be quiet! They're on to me...
"Open your eyes, my friend, and you shall be set free"

I take their advice and find myself in a foreign land
Demolished buildings kept secret under the sand
A war zone by the looks of it
A place that has been hard hit
Suddenly, the earth starts to shake
Double vision, everything quakes
Soldiers appeared, they came running
Sharp-tipped rifles pointing,
I find shelter, protecting me from the spitfire
Hidden under all the chains and barbed wire
A single extremely excruciating spike
Scars at the bottom of my brain: "PSYCH!"
