New Disclaimer:   This theory seems to be gaining momentum amongst the community, many are now accepting it or at least thinking over it seriously.  However no matter how many of us believe or whether it becomes the main philosphy of the community, it is only the belief of ours, we are in no way saying it is the reality for all multiples.
 

With that said I have been thinking lately about how real our internal world is, how that it has its only history, culture and religion.  It seems more and more like a real place, like a part of a bigger world, and that got me thinking.  We all remember this story from our past, although not sure now whether it was one told on the inside, or something we saw on television, or read in a book.  It was a story of an old house and the back garden was overrun but those brave enough to travel through the scrub found an old rusted gate.  If you push it open and walk through you find yourself in another realm, an alternate universe, a fantasy land.  We loved this story.

So this made me think.  What if this body wasn't multiple?  What if instead it was like a portal, like the gate in the story?  The connection point between two worlds.  We know now that the person borne into this body died when she was three.  So I wonder if leaving it empty created a pathway, that instead of the body dying with her, it became a conduit to this other world.  That we live there and are only vistors in this one.  In our world there is this pathway, leading from the Shire through the woods to a type of bottle neck clearing, it is from there that we step over a line and enter this body, is that the gateway of our story?

Idia, the land from which we come has a long and detailed history.  It has a culture and mythology of its own.  As stated we believe in that to be as real as this world.  So take that one step further.  What if it is real.  When Carole died at age 3, from the abuse she was suffering at the time, what if at the moment her essence, her soul died the body was entered from Idia.  We believe the essence of the person returns to the Source moments before the body ceases to function, it takes a while for the heart to stop, the cells to die, so in that moment, for a split second the body was alive but empty, allowing the person in Idia to come through the portal into the body that inhabits this world.  Up to this point Carole blocked the path, and maybe if she hadn't of died the portal would of never been free.  But she did, and the next person in found herself in a world she didn't know, and in a horrendous situation.  From there the 
"Wildnerness Years" started, the people of Idia scattered into the woods.  I believe the opening of the portal sent waves through the community on the other side, devastating it for some time.

The residents of Idia, both human and creatures, have never felt like they truly belonged in this world.  There was always something that just didn't fit, like it was slightly out of step.  We remember Kate trying to explain it to our therapist, she actually said it was like she got transported from a foreign world to this one, that it all might look the same but the rules were different, that no one quite understood her beliefs.  And Kate is one of those that questions this theory.  The creatures, for the lack of a better world, also don't seem to have their match in this world's mytholody.  I hear about elfs and faeries here to mention a couple.  They seem to have a distinctive appearance or culture.  We talk about Rahs and ShadowWalkers, WatchTower Guardians.  Things I have never heard about in this world, some do not have corresponding creatures.  But we know their history, we can spot them by appearance.  If you see a Stone Rah it is obvious that he or she is one.  We know what they are, what their species means.  All the people and things from Idia, feel a connection with there that they have never felt with this world.  And although we say our family, my mother, whatever, it is said more for social acceptablity rather than any real felt connection with them.  No one here feels they are part of that family.

Then there are the siblings, the twins, Guardian and Censor.  We have never fully been able to understand those two.  They were enigmas, part of our "multiple system" but never part of the community.  They lived beyond it, the rules didn't seem to apply to them.  They spoke in half truths and riddles.  We now wonder if they are Guards of the portal, managing the movement between worlds, working to keep it running smoothly and ensuring the rules of behaviour are upkept.  They seem to have no juristinction over Idia, do not get involved in what happens to us in this world.  But rather they seem to observe everything of both worlds and make sure we behave as required.  They will remove words we are not allowed to speak, they have been able to banish people from use of the portal.  At first I didn't know if this made sense but discussing it on the DarkPersonalities email list, I got a response that corrobated this belief.  Ok it was only one, and it is still a theory, but it helps for someone to believe in this possiblity as well.

So are we multiple at all, or are we a community of people that have found a way to travel between worlds.  Its just an idea.
