NOTE: Some of you may have already seen my interview with Dia Renalda. In it, I mentioned the phenomenon known as "dimensional bleeding", but didn't explain. So here's an explanation now. --SΣ
Description: This is the phenomenon that causes parallel realities to "bleed" into one another, allowing people living in different universes to interact, and causing a number of inconsistencies, particularly with the appearance and behavior of PREs. "Dimensional Bleeding," as the phenomenon is colloquially known, is usually most noticeable in the presence of a PRE.
There are a number of hypotheses among Archive Analysts regarding the source of this phenomenon: some believe that the PREs, by their very presence, cause a breakdown in reality. Others hypothesize that it is the opening of Pathways that weakens the boundaries between universes. Still, there are some who believe that the phenomenon is solely a side-effect of PRE19 "Quiet".
