Stifle

  He haunts me
Quietly in his corner
All sound muffled by his enigmatic essence
His piercing eyes glowing with critical judgement
Constantly stifling all emotion by mixing and masking feeling with fear
The air that surrounds him is dense with despair and failure

His presence is obvious and repulsive
But any effort to conceal or approach him is futile
His intangibility is what is most frightening
However many have tried to ignore him have failed miserably
For ignorance towards him
Is ignorance towards life itself
Believing he doesn't exist leads you
Hand in hand with Death.

Reviews

As requested, here to help, review, and give the best and as much of a constructive response I can possibly create off the top of my head.
I find that the poem created here is a representation of the life of the writer whom finds himself plagued by the job of Death's existence.
You can try and ignore him, run away if you like, but your poetry here says that we are a being whom cannot removes ourselves from the death's sight or grip. It really goes more so for a religious experience of enlightenment of Death and how it effects our lives rather than the religious concept of Demons and possession as explained by Overwhelming C. I think... that's of course only opinion and perspective of my own on the topic of the poem with every respect to the other reviewer's judgment. I find it a well done scholar like poem with the intention to inspire a provoking thought within the reader. A well done job indeed.
Some things to point out though is that some lines are over-exaggerated and break the rhythm (ex: lines 2 and the transition to 3) and missing in technique, although it uses great description and word usage (fancy adjectives, etc). The best advice here is to study formal structures of poetry... learn stuff with syllable counts and meter (teaches poetic rhythm and beat), and learn various techniques such as end rhyme, assonance, consonance, alliterative verse, etc. most of which can be learned here:

Conclusion:
With a little bit of work and studying, I find there's great potential for a poet in the works here. Keep up the good work ;) and don't take any constructive criticism to heart, it is only meant to help better your skills as a writer.
Like a whetstone to a sword, so is words of advice.

To me this sounds like someone who has embodied the 'spirit' of the 'Devil'. "Believing he doesn't exist leads you Hand in hand with Death." That's what made me think the devil or something was being involved and then, "His piercing eyes glowing with critical judgement Constantly stifling all emotion by mixing and masking feeling with fear". I figured to be someone close to you, someone you see everyday, possibly a father figure or perhaps a demon that dwells inside of you. Like the demon that's within all of us. The mark of humanity? A stain of original sin placed by unseen forces as an obstacle that must be over come to experience the true meaning of life? Thoughts run deep. Your poetry provokes unorthodox thinking to figure out the truer meaning of your literature.
