The connection lies with the nature of the world itself. Think of it as a simulation program. When you enter the room, you are the only entity there that 'does not belong'. Such is the case here, we do not belong, and therefore everything else is linked. The wings and the journals can be assumed as a method to keeping us apart of that link...

But as I said... it is merely a working theory. Somehow the memories are effected in this process... and prolonged exposure to this place may even be effecting our... 'personalities'...
