Does this story sound good?

a little story thing i made, i kinda am starting to get interested in this stuff even though im hoping to be a history teacher.

Nightmare

Once i had drifted off into the this perplexing dream state that i was in i started to feel as though i was in this sort of elated state of mind, nothing could ever bring me down. Then the feelings, emotions, joy, everything was gone in a split second. I felt as if someone had took a blade a stabbed pierced through the very being of my soul, as if they had took me down in one fatal blow.

I looked around all around me to find that this world that had so many extravagant and amazing things had turned into something that was full of death and the feeling of darkness eating away at my soul.

When I slowly started to walk my way towards the darkness i started to tremble when the darkness gets closer.....and closer....and closer until i am consumed by this darkness until i see nothing, all i see is a black void full of nothing, no emotions, no people, no animals, nothing but just darkness.

After feeling like century's in this lonely place full of hatred and despair i feel something tug on my leg and then devastating pain, i see that arms are taring me to shreds. I see a man in the distance laughing as though he finds this to be great entertainment. As the man walks closer i start to notice that he is no man but he is some demonic being. When he gets only inches away from me he smiles with a smile i will never for get, so menacing, so demonic, it makes my skin crawl just thinking of it.

He opens his mouth and then lunges at me but right before he bites me i wake up, hot, scared and trembling in fear. I think to myself "it was only a dream, none of it was real." Then all of a sudden i hear a very deep and fearful voice behind me say "Oh yes im just a dream", I turn around quickly and see nothing there but i feel a deep pain on my neck, I run to the bathroom and look in the mirror. I see teeth marks, they dont look human......

So tell me what you think! Be honest! :)
