How exactly does one get into the Realm of Sleep? How did Sora and Riku get there? The game begins with them on the Destiny Islands, after Yen Sid's magic transformed them into their younger form. But is this in the Realm of Sleep or is it just normal Destiny Islands? And is it in the past or present? Braig says very clearly and unmistakably that Sora was "able to go back in time to just before your home became a Sleeping World", I'm assuming in order to ride the destroyed Destiny Islands into the Realm of Sleep. However, YMX specifically told Sora:
"To move through time, you must leave your body behind."
I assumed Sora and Riku still had bodies since they traversed both real and dream worlds over the course of the adventure with no problem. But then I wondered, are they going heart-only style like Sora in CoM? What would that mean? Is Roxas back, then, along with a Riku Nobody? Or did Yen Sid just use a magic plot exception and transported them back body and all.
To make things worse, Sora and Riku open a keyhole of sleep in the Destiny Islands. If the world was awake how is that possible? That seemed to indicate that it was sleeping. But if it's sleeping how did they get there? Or were Sora and Riku riding it into the Realm of Sleep and then the Keyhole appeared?
Furthermore, why did Xehanort's Heartless have to go to the Destiny Islands on that night? If the scene on Destiny Islands is in the past, it makes sense, since Young Xehanort needs to get to the entrance of the Realm of Sleep, but can only travel to places/times later incarnations of Xehanort have been to. However if the Destiny Islands scene is in the present, it really makes no sense at all. And if it's in a dream I don't have a clue what to make of it.
tl;dr: Does anybody understand how Sora, Riku, and Xehanort got into the Realm of Sleep?
