The various dimensional frameworks that operate across the multiverse—not just the 3+1 dimensions of our spacetime, but the full range of dimensional possibilities that different universes might contain. Some universes might have 4 spatial dimensions, some 11, some none at all. Some might have multiple time dimensions, or none. The concept of multiverse dimensions acknowledges that dimensionality itself is a variable across the multiverse, not a constant. Our 3+1 dimensions are just one possibility among infinite. Multiverse dimensions are the ultimate expression of "things could be otherwise"—even the most basic structure of reality is negotiable.
Example: "He contemplated multiverse dimensions, imagining universes with 4 spatial dimensions where you could reach inside a locked safe without opening it, or with 2 time dimensions where you could experience past and future simultaneously. Our universe felt suddenly cramped, limited, 3D. But it was home, and home has its own beauty."
