Higher or other dimensions.

I have heard many metaphysical people that believe in afterlife, psychics, and the like talk about other dimensions or even higher dimensions. But what exactly do they mean other than places that aren't here? To my knowledge dimensions are only things that have been applied to mathematics? — TiredThinker
Before the 20th century, the meaning of "Dimension" was obvious : a physical measurement, typically expressed with a vector of compass direction & measured magnitude. Then, Einstein muddied the waters by merging the three spatial (physical) dimensions with the singular temporal (mental) dimension. Next, Quantum Theory proposed the physically-vague-but-mathematically-useful notion of Meta-Physical (mathematical) Fields, imagined as extended in space, but consisting of 0-dimensional points that are defined only by reference to an imaginary grid. Eventually, the hypothetical notions of Many Worlds & Multiverses extended the range of discussable dimensions to infinity. Meanwhile, the Physical meaning of "Dimension" has been applied to various Meta-Physical (mental ; non-physical) postulations.
Last year, TPF had a thread based on the notion of a 5th Dimension of Mind/Consciousness. But when I asked the poster for a specific definition of that "dimension", she refused, on principle --- implying that I should just accept it on faith. She also declined to describe how that "dimension" could be measured. So, I concluded that she was simply applying the "5th Dimension" label to the ancient concepts of Platonic Ideals (potential Forms) and Aristotelian Metaphysics (ideas about ideas). But they weren't talking about "afterlife" or "psychic phenomena" and such.
Therefore, I concluded that postulating a "5th dimension" was merely a sneaky way to make metaphysical concepts sound more sciency. Personally, I find "Idealism" & "Metaphysics" to be more useful terms for talking about mental objects (ideas ; Philosophy), but not for discussing physical bodies & forces (corporeal ; Science). Since the topical subject "matter" of Mathematics is ideas about immaterial philosophical abstractions, it is a proper venue for discussions about higher dimensions. But, due to the non-physical intellectual nature of such abstract concepts, as with all philosophical postulates, we need to be willing to carefully define terms. And to expect some skepticism about things you can't put a finger on.
