Nobody seems to really believe that story, although the medical staff seem to believe the story themselves.

Personally, I think it's more likely we're simply bleeding through the walls of the universes - whether it's a natural phenomenon or someone is controlling it remains a mystery, because we are unfortunately trapped on this island. There's a forcefield caging us in, one more powerful and advanced than anything I've ever seen before - and I've been all the way to the end of the universe before!
