A perfect world: an impossible dream, but one everyone wishes for at some point. You did a great job with the poem - it flows quite nicely, and the words capture how we all feel, wanting the world to be like that. Keep writing!

"But it isn't reality, it's only a dream." That's very true. We all experience 'good' and 'evil' in our lifetime, but I think it's still important to 'hope' or 'believe' that the world could be a 'better' place. Otherwise, we'd all just give up. Keep up the good work. :)
