parallel universe theme

also known as: parallel dimension, multiverse

A hypothetical self-contained universe co-existing with our own.

Notes

The word "dimension" is used in two different sense in fiction. Sometimes what is meant is no different from a parallel universe. Sometimes what is meant is a fourth spatial dimension of space as an addition to the three we know. In the latter case we use "four-dimensional space" as a theme.
