To discuss the perception of entities in higher dimensions, I think it's helpful to start with some fundamental concepts:

Point Particle: When I think about a point particle, I consider it a theoretical concept in physics where an object is thought to have mass but no spatial dimensions. For me, this means the particle exists at a single point, with no extension in space.

Two-Dimensional Beings: In Edwin A. Abbott's Flatland, I see that two-dimensional beings exist only on a flat surface. These beings can move along this plane but have no concept of a third dimension. For them, moving up or down doesn’t make sense, which I find intriguing.

Three-Dimensional Beings: I, along with everyone around me, am a three-dimensional being. We interact with objects that have length, width, and height. To me, this means we can move in all spatial directions, and our perception is based on a three-dimensional experience.

Four-Dimensional Beings: When I think about four-dimensional beings, I imagine a concept where there’s an additional spatial dimension beyond the three we know. In physics, I understand that the universe is sometimes described as a four-dimensional spacetime continuum, where time acts as the fourth dimension. If I could interact with a four-dimensional being, it might access the inside of a sealed bottle without needing to open it, which I find fascinating.

The big question for me is whether humans could ever perceive or interact with entities from higher dimensions. Right now, I feel that our understanding of dimensions beyond the third is quite limited, and our sensory capabilities are confined to three-dimensional space. The idea that there might be individuals who can sense or interact with higher-dimensional entities is speculative, but it's a topic I find intriguing and one that continues to spark my interest, even if it's still far from concrete evidence.

An interesting speculation but I have some doubts. Flat people would notice a 3D being if one came into their world because a 3D being inhabits also the two dimensions of 2D. We would also notice a 4D being. Furthermore, no one has ever met any flat or dot beings.

I see this as a putely abstract mathematical concept.
