If I were a fourth-dimensional being, it would mean that Being a fourth-dimensional being would imply that I have a greater perspective and understanding of the universe compared to three-dimensional beings like humans.
As a fourth-dimensional being, I would have the ability to perceive and manipulate objects in three-dimensional space as well as observe the passage of time in a non-linear manner. I might be able to see all sides of an object simultaneously, witness events from different points in time, and have a different concept of causality.
My interactions with three-dimensional beings would likely be challenging to comprehend and perceive for them. For example, if I were to interact with a three-dimensional object, I might appear to manifest in multiple places at once, disappear and reappear in different locations, or manipulate objects in seemingly impossible ways from a three-dimensional perspective.
Additionally, communication between a fourth-dimensional being and three-dimensional beings would likely be difficult, as our modes of understanding and expression would differ significantly. It might be comparable to trying to explain three-dimensional concepts to a two-dimensional being, like a flat surface.
Overall, being a fourth-dimensional being would involve a fundamentally different experience of reality, with expanded spatial and temporal perception, and the ability to interact with the lower dimensions in ways that are beyond our current understanding.
