really have characters? I mean, you say we can't control other's characters, but what exactly are we? You said this a an imaginary world in a child's mind, so as you described, it's kinda surreal, but remember even in child's mind, things must have a meaning,so.. we can't just put random madness into this for no reason.... so... I think you could write a little more about Sky, so we, RP'ers could roleplay as different characters ( which since this a surreal world, could be human or not) that in every way would represent Sky's reality. A trauma of his? Doubts (commons in every child ^^)? Fear? Loneliness? Lack of comprehension?
-Hey, this really reminded me of Alice in Wonderland (I never read the book, but I know about the story and saw the movies^^)
So, you can PM telling all of your opinions and others ideas you already have for this.
