Everyone, to add more to this discussion it just hit me about the Room of Sleep and Awakening...
Could it be... Xemnas was using the room he created to access the Realm of Sleep? Or at least the period of time written in Book of Prophecy?
But why? Was he actually able to enter the sleeping world? And if he did what was he doing? Is he related to Luxu, apart from the connection to Xehanort? Even Xigbar was unsure what he was doing in there, and apparently they are meant to be working together.
But then again, it has been hinted that each Xehanort has their own ambitions and intentions so.. They are all hiding something from each other.
