Higher-Dimensional Existence

Summary
Higher-Dimensional Existence or Dimensionality is a given object or entity is referred to as being higher-dimensional when they exist as part of a system with a number of coordinates axes greater than our own, or in layman's terms, if they possess more than three dimensions.

Speaking in simple terms, a "dimension" can be considered an axis of movement and measurement, through which beings and objects can displace themselves throughout a given physical system. 1-dimensional beings would only be able to dislocate themselves to left and right across a single direction, while 2-dimensional beings would have an additional spatial axis inherent to them, and thus be able to move up and down as well. Finally, 3-dimensional beings like ourselves are able to displace themselves left and right and up and down, as well as forwards and backwards, encompassings parts of additional axes of space.

Following this same principle, a 4-dimensional being would be capable of moving through an additional, perpendicular direction incomprehensible to lower-dimensional beings, and this can be generalized unto any higher number of dimensions.

Applications
Keep in mind that this is merely a very general list of the abilities that a higher-dimensional entity would possess, and is not necessarily applicable to all of fiction.


 * Pseudo-Invulnerability: Due to the additional axis spatially inherent to them, higher-dimensional objects are comprised of more information than what can normally be described in lower-dimensional spaces, and thus may only be capable of interacting with them through lower-dimensional "slices" or cross-sections of their bodies.
 * Pseudo-Teleportation: Higher-dimensional entities may be capable of seemingly phasing in and out of sight by moving through additional axes imperceptible to lower-dimensional beings, granting them a notable advantage in overall range and mobility.
 * Unconventional Physiology: Although much of the same physical laws and principles would theoretically apply to higher-dimensional worlds, they would likely be instantiated very differently, resulting in matter behaving in strange ways compared to our own Universe.
 * Large Size: Due to the additional angles possessed by them, higher-dimensional objects and beings would be much larger than lower ones.
