Ethereo-Spatial Rift is a term from Ghostbusters: The Video Game (Stylized Versions) that explains how rifts to the ghost worlds are formed.

In areas where the wall between the physical plane and the ethereal is thin enough, certain paranormal entities can expend the energy to tear a hole between the two. Once a rift is opened, beings from either side can freely step through and appear wholly in a parallel dimension. This method of travel is hardly advised, as there's no telling where one portal might lead and what being might hold dominance over the destination.
There was a brief period when Ray and I, fascinated with our encounter with Gozer, experimented with opening portals to alternate dimensions. Needless to say, we will no longer be exploring that avenue of research and it is fortunate that the square block we ran our tests in was going to be leveled for construction anyway. Ray assures me that denizens of the sixth dimension needed those tenement buildings more than we did.
If you plan on experimenting with these, be sure to pack for a very long trip.
The art page can be found in NYC Public Library, during the "Welcome to the Gozerian Public Library" section. It is hidden inside a bookshelf in the area where you begin the level.
