Outlandish Sci-fi Horror

Do you ever look at the world with new eyes?
Do you ever wonder will happen when our world dies?
Living on autopilot is our main man in this tale
His name was John Dale
He plotted his life all out
Wife, house, son, bank account
Nothing in his life was ever in doubt
Then one day, he comes home
His wife looks grey
Her face morphed before his eyes
His reality was in disguise
His life full of lies
His son was dead
She'd ate half his head
Then she turned to him and said
We were waiting for the right time
To strike and now your mine
She leapt on the kitchen table
Let out a deafening whine
He grabbed a knife from the kitchen top
In the space of 3 seconds thought a lot
What the fuck is going on?
Back out the house he was gone
Perfect wife, son and life
Everything gone in one
He drove off in his BM
His wife ran out after him
But Thomas managed to escape
The clouds above were no longer in shape
They were distorted and red instead
Dead bodies were floating high
The clouds were capturing them in the sky
His car and other vehicles bashed about
He panics then starts to shout
A stranger comes to grab him out
The car goes up as John pulled down
The strange says this is just the start
His steady expression turns to a frown
Your just one
Of the chosen one's John
I've been seeking you out
It's not over yet
We can win
I'll just say let your training begin
