Page "Plane (Dungeons & Dragons)" Paragraph 37
from
Wikipedia
Planes may border ( be coterminous ) or may be coexistent.
In particular, the Ethereal and Shadow planes are coexistent with the Material Plane.
In effect, the " boundary " between the two extends through all of space.
Thus a ghost in Dungeons & Dragons, which is an ethereal creature, has a location on the Material Plane when it is near the border of the Material and Ethereal planes.
It can " manifest " itself into the Material, and force attacks launched from the Material can hit it.
