no the dimensions are the samsara, the 6 or so co existing dimentions, god realm earth realm etc, that is from certain buddhist teachings and sects, not daoism, the dao philosophy and following resides in the scripts from the tao te ching, and lao tzu.
there is no heaven and hell to daoists, just the real universe that we can study, and the empty force that holds form tot he whole universe, the ever changing universe, the unseen energy that runs through everything, the dao,
the buddhist teaching of samsara is not daoism, confunctionism buddhism and taoism are mixed and jumbled up in china they are not seperated all are accepted at the same time,
there is no god, heaven or hell in daoism,

quote from link "TAOISTS do not believe in the Wheel of Life of the Buddhists nor in the Heaven or Hell of Christianity. "TAOISTS view existence as glorious. The whole Universe, they teach, is a marvelous, vibrant Unity wherein everything, visible and invisible, pulses with energy and changes. As being develops through the experience of existence, its vessels ... are swept onwards by the mighty stream of the eternal TAO to other forms of expression and activity. Man does not die; he merely extends into new fields ."
peace.
