Vibrational Attunement
From Multiversal Omnipedia
Vibrational Attunement is a method of interdimensional travel, wherein the traveler (or the vessel they are inside) changes the vibrations that keep him in place in his home reality to that of another, thereby transferring to that other reality.
Comments
This form of travel was also used in the pre-Crisis DC multiverse, although it was not named as such.
