/r/nosleep thoughts
at this point the narrative completely breaks down, and it's revealed that the author is writing this at the behest of the creature from its weird pocket dimension where it has been subjecting the group to unearthly suffering, extremely reminiscent of I Have No Mouth And I Must Scream.
there's no plot, no explanation, no resolution. I can't really say if it's bad or just strange. but it was just confusing and disturbing enough that it stuck with me
horror, Occult 2009 film spoilers
another example is the found-footage horror film Occult directed by Koji Shiraishi, who did Noroi and Sadako vs. Kayako. the film gradually builds dread, but it is infamously "ruined" by the last 30 seconds: a cartoony animated scene showing a weird aquatic hell dimension. it's jarring and easy to laugh it off when the director has some immature and gratuitous films under his belt. but if I think on it long enough I can get that same intense feeling of unease.
horror, personal
there's a specific niche in horror of the absurd. where there's a 50/50 shot of it being so bizarre that it's funny and ruins the tension entirely, or it lands and makes you scared/uncomfortable.
I only had nightmares until I was ~10. I distinctly recall a few that shook me in this way, but people laughed me off and left me feeling frustrated and alone. I think this horror hits me so strongly because it feels like childhood nightmares, and I'd venture to say that's the intent.
