the.com/hall of mirrors

means A situation or place where reflections, repetitions, or distortions make it impossible to tell what's real, original, or true.

from Literal hall of mirrors rooms were engineering spectacles of mirror-making, the most famous being the Galerie des Glaces at Versailles, where mirrors faced windows to multiply light and space. The figurative sense — for political spin, media distortion, or self-deceiving thought loops — grew from the funhouse version of these rooms, the carnival attraction where warped and multiplied reflections disorient visitors; by the 20th century writers and journalists had seized on that funhouse image as a ready-made metaphor for propaganda, paranoia, and any situation where you can't find the one true image among all the copies.
