Spider Woman is a metaphor for she who creates from a central source. One day it is She who will pull all of her creation - back to her source. Her web represents the grids or matrix of our reality - the Spider Web Effect. Spider Woman's web links you to everything and everybody in our reality. It is how we learn to be psychic and to connect telepathically.
The Spiderweb Effect means that all things originate from a central source, spiral out in a matrix, grid, lattice, or web, following the same geometric design, are connected to each other and that source. That is, if something affects one part of the web, it affects everything.
