Analysis of Pilgrim

I am a pilgrim
Often I delve into the future
And life is at its bay
The trees are green,
Even the fruits are ripe to savor.
The flower blossom
Waving at the sun, their dearest
And smiling at the butterfly.

Then back into the dysphoria of the past
Which has determined to haunt me
 with imagery of a human carcass
That I hunted down in my diminutive stage.

I am deluged by its echo
As it reverberates and scribbles
On the wall of my heart.

Now I am in today,
Taking a step at a time
Making bricks.
