Watching the seventh season, so I might be missing something, but I feel like the only way the hidden world within 수퍼내츄럴 remains unnoticed is because the world is populated 의해 idiots.
I mean, the Winchesters have been caught on camera time and time again on the news, when a Doppleganger 또는 Leviathan is posing as them committing murder. While the tape of the first “Ghostfacers” episode containing them is destroyed before it can be spread to the public, the Ghostfacers are shown to have mentioned them in their web series during that one episode where Zachariah makes Dean and Sam forget their lives and rediscover hunting. Not to mention the 수퍼내츄럴 book series that Chuck publishes. Do the 팬 just miss the fact that there are a couple of serial killer brothers with the exact same names as their 가장 좋아하는 characters on the loose? Hell, the 책 go up to season 3 finale. Did the 팬 miss the news reel that plays out exactly like the book? Not to mention Chuck probably also mentioned the Ghostfacers entire crew 의해 name before they were shown on the Ghostfacers website. A 수퍼내츄럴 팬 (in the canon universe, obviously) could see the Ghostfacers were real people, the Winchesters are real people, and many of the characters mentioned in the books, including Agent Henriksen (who was mentioned in the newcast when Lilith destroyed the town jail holding Sam and Dean) and the people who Sam and Dean saved. Then they would show them the 수퍼내츄럴 series, and 더 많이 and 더 많이 people affected 의해 the Winchesters rally behind this movement, and Shabang, Shaboom, the whole 수퍼내츄럴 world and all its knowledge falls in on itself.
