demidimension

Demidimension is a term that has appeared in various fictional contexts, often referring to a parallel or alternate reality that exists alongside or partially overlaps with our own. The prefix "demi" suggests a partial or half-dimensional state, implying that these realities are not fully independent or distinct. Instead, they might be characterized by subtle differences, altered physical laws, or a limited set of inhabitants.

The concept of a demidimension can manifest in different ways. In some stories, it might be a place where events unfolded differently, leading to a divergent timeline. In others, it could be a pocket dimension or a plane of existence with a less stable or less defined reality than our own. Access to a demidimension is typically depicted as difficult or requiring specific conditions, such as portals, magical artifacts, or mental projection. The nature of interaction between our dimension and a demidimension can vary, ranging from mere observation to direct influence or even invasion. The term is more common in science fiction and fantasy literature and media than in established scientific theory.
