Dimensions

A dimension (also called a plane, world, realm or universe) is a self-contained universe. Together all dimensions constitute the multiverse.

Afterlife Dimensions
Afterlife Dimensions are dimensions that can be populated by souls of the deceased, though these realms are not necessarily entirely populated by the deceased. Human souls often go to an afterlife dimension depending on what culture they were from, what religion they followed or what god they prayed to. For example, humans who follow any kind of Abrahamic faith (Christianity, Judaism or Islam) go to either Heaven, Hell or Purgatory depending on what kind of life they lived before they die. Greek and Roman souls often go to the Underworld when they die, where they will either go to the Elysian Fields, Tartarus or the Asphodel Meadows and so on.

Pocket Dimensions
Pocket Dimensions are dimensions that exist within another dimension. They are sometimes called 'overlapping dimensions'. An example of a pocket dimension would be Limbo and the Astral Plane, which exist within the Earthly Dimension but are considered separate dimensions.
