Temporal Shift refers to a concept that we can move into or from space
and time that is not our own.. ie parallel universes

Dimensional shift sometimes refers to an ability to make use of other
dimensions, we exist in 3 dimensions , and have accepted a fourth
dimension of time , but string theorists predict that the space we
live in has in fact many more dimensions (frequently 10, 11 or 26).

Ultraviolet the move uses this concept quite nicely  ppl "store" items
eg guns and swords in another dimension..  to conceal them
