Dimensions

Attached to each BZPB universe is a set of adjacent dimensional realms with certain functions and properties.

In BZPB, the difference between universes and dimensions is that while universes contain stars, planets, other celestial objects and (mostly) conformed to the laws of physics, dimensions need none of that. When a character enters a dimension instead of a universe, their physical form changes to fit the rules of the dimension. For example, if the dimension appeared to be 2D instead of 3D, a 3D character entering it would appear as 2D for the duration of their stay.

Some dimensions fulfil certain roles in the workings of their respective universes; for example, evil souls from the Original Universe can go to the OU's respective Hell upon death, and the consciousnesses of sleeping humans in the OU are known to connect to the OU's Dreamworld while asleep, where Dreamkeepers battle Nightmares to keep them from plaguing human minds.

Not all universes have the same dimensions - for example, a universe which doesn't contain the Zivon may not have an associated Realm of Shadows.

In addition, it is possible for only one version of a dimension to exist within the BZPB Omniverse as a unique entity. A good example of a unique dimension is the Knowledge Dimension.
