Alright, critique away, wrote it when I was drowsey and tried to write down what that's all about.

lost in an emerald dream
the dark green surrounding me
wandering fog filled paths
though not discerning a thing
mind disoriented and misplaced
the rayless sky perplexing
i hope i never wake up
lost in an emerald dream

I know that it needs a little more length and rhyme, what else though?

my mind's really blank at the moment to give you a decent comment but even in my blurness, I pretty much liked it. Simple yet sweet.
