The dimensional ladder is not a model of experience; it IS experience. Eight stations, from pure attention to recursion. Integer dimensions are what experience settles into. Half-integer dimensions, carried by i, are experience happening.
i rotates through all four processual dimensions. That rotation IS experiencing. The integer dimensions are what experience crystallizes into; the half-integer dimensions are experience itself: the gathering, the turning, the unfolding, the closing-that-becomes-opening. At every scale (a single thought, a conversation, a life, the cosmos) the same octave plays.
