I know its been asked....but what is GR's concept

I had a proper in depth listen to it the other day and for some reason or another (i really don't know why) I suddenly felt like this album is about one story being told from 3 perspectives. Possibly it's just because the three songs "tBotH", "BtM" and "Reverie/Harlequin" forest are connected. But when i suddenly applied that theory to it, the whole album sort of made more sense.
