Each world, the Overworld, Physical Realm and Underworld, are separate worlds with different planes within each world. Each plane has its own beings as well as certian frequencies.
The frequencies are marked as either +(positive) or -(negative). This is not to say that the positive (+) beings in different planes are all good, just as the negative (-) beings in different planes are not all bad. The frequencies are really the vibrations of a certian plane and of the beings within that plane.
The physical plane is the plane with zero frequency/vibration. In other words it is neutral (~).
The planes are mirror images of our own physical plane, but with each degree of separation from our own plane, and the individual planes are altered in their own way. Each spirit type is incapable of manifesting fully outside of its own realm; however, with a few exceptions, they are capable of affecting realms within a certian radius of their own. Again with each degree of separation their influence is altered and often weakned.
I got this information from a book called Witches Book of Spirits.
Sort of interesting with this Author’s take on all of the different realms and planes of existence… I believe it is even more expansive and diverse than what is said above…
