Crazy

Just give me a reason
For letting you ruin my sanity.
I took it all away from you
But now you know where you stand.
- Quite dark right off the bat. I don't have trouble understanding this, however, it feels like simply four sentences that have been positioned below each other. There's little flow, it doesn't give an impression of a poem.

I still hear voices in the rain.
Tantum ergo sacramentum.
For all of my pain and anguish,
These words really are quite innocent.
- Latin, ey =) I wish this had better flow though, it's ruining the magic this poem could have; it's just not that intriguing to read, you know.

There's an uneven lapse of not knowing, here;
These softly spoken words in the air,
You don't understand. But you easily fear.
But they're beautiful words.
- I think I know why people sometimes do not understand what you want to say or show - you're being rather abstract without any solid hints. While I pick up some and I'm not exactly lost, I'm not exactly sure I'm getting the right picture though - and it might be worse for others.

As about the flow, it seems to have somewhat improved, but the last verse is breaking it a lot. Rewording or using adverbs like 'such' make a lot of difference - in the tone, in length, in the flow.

Try not to judge my illusions,
When you read these words again.
Just listen to the music,
And let me sing some pain.
- Well, here the flow is somewhat 'smooth' and easier to understand too, but the reader might be already lost in your abstractness.

These words were sung softly, sweetly, down my ear.
Let them wash over you too.
I heard them in the rain. I understood.
I knew you wouldn't.
Just then remember to forget what you see again,
For my world is full of more pain and suffering than you can understand.
- Prose in poetry, alright. Shamefully, not well executed. I just can't feel any impressed nor interested in rereading this, remembering this. It's a shame, really; there's just no magic nor impact, even though the message is heavy.

I can't stay here.
I'm selfish for wanting to run,
But in death, for me,
My life can't goes on.
-Oh I hope you mistyped 'goes' in the last verse. In comparison to the all previous stanza, this is closer to the whole 'impress, intrigue, smooth read, flow' I've been talking about. It's a fairly good ending too, so not much to nitpick.
