Thanks krexia and Lancelot!!!Darkness becomes light,
Light falls into darkness.
Dreams are connected to each other--
When you fall into a dream,
You are connected through dreams to "The world enclosed in sleep".
And if you open the "Keyhole of sleep" in that world,
The world will be released--
Ok this is what I got from that, Sora and Riku are in the world enclosed by sleep there dreams are connected to those in the "Realm of Sleep" and when they open the "Keyhole of Sleep"the bonds they made in the RoS will become reality. I see that as a way for there interaction with people in KH3D to hold up instead of it being a self-contained adventure.
