The little bit I did about geomancy and spiritualism puts me in mind of an issue that is mighty important for a working spiritualist/magician/shaman/etc. There are many spiritual worlds and while many of them abut and overlap our own world, they are not precisely identical with it or each other. Yet, because there does seem to be some basic cosmic entanglement through their unity in God, there are many parallel patterns. That makes it easy for us to confuse one world with another, one spirit with another. We can hear them described and position them within the spiritual world or worlds with which we are familiar without actually knowing whether they belong there or belong to a world parallel to it.
