of course, I've always liked the macabre. I see where Mark gets a bit confused, but I understand where you are going with this. I'm thinking that you are saying that your new [life] is a new game, full of different direction than a mortal life. There are some restrictions of course, and one of them being that you must be safe from the daylight. Here's what I would say about a couple of lines.

I am [now] for the future, for the past I am dead.
I feel the power of night and of the moon.
It's unfortunate that sunrise comes way too soon.
Capitalize all your I not just some of them.

I feel the mood of this piece!

The last line: "but unluckily the sunrise is coming to soon"
This line envision the total awakening of the dead when rapture shall take place. I just pictured the imagery in this line. Sunrise is a new dawn for the coming of the Lord Jesus to bring out those who was dead many years ago.

Beautiful!
