A recent trend in online photography communities has been the imaging of liminal spaces, with the intent to convey "a sense of nostalgia, lostness, and uncertainty." The phenomena gained media attention in 2019, when a short creepypasta originally posted to 4chan's /x/ board in 2019 went viral. The creepypasta showed an image of a hallway with yellow carpets and wallpaper, with a caption purporting that by "noclipping out of bounds in real life," one may enter "the Backrooms," an empty wasteland of corridors with nothing but "the stink of old moist carpet, the madness of mono-yellow, the endless background noise of fluorescent lights at maximum hum-buzz, and approximately six hundred million square miles of randomly segmented empty rooms to be trapped in." Since then, a popular subreddit titled "liminal spaces," cataloguing photographs that give over a "sense that something is not quite right," has accrued more than 117,000 followers.
