Analysis of Dark whispers

Dark whispers inside of my walls
Some  days it appears much closer
On the other side of the  wall
Some words negative  
Brought with  a laugh  and a smile
While evil subsides
And jitters a while
What appears to be friendly
Was like a murderer
Looking in your eye.
But the voice from with in
Had a prayer for the child
For he was taught what he knew
Not what he felt in his heart.
What he really needed
Was a brand new start
