I can't find it now (found it, check comment below), but when I first learned about peertube, i found my way to this strange, almost otherworldly video. Everything was blurry and dark, and the sounds of tearing fabric were ever-present. I have no idea what it could have been, but it had this distinct feeling like I shouldn't have been watching it. I think about it every now and again.
Update, through some hardcore scouring, I did find it. You can watch it here. A friend I was talking to said it might been an AI-generated thing, which would make sense, but I'm not certain. Checking the profile, they've only uploaded this one video, and they seem to have a bandcamp with no real information about themselves or why they've made this, but they've got a few other audio-only tracks that are kind of similar, only much shorter.
Nice. PeerTube instances have gotta be among the stranger spaces of the fediverse if only 'cause they focus on video. It's not as strange but I stumbled into finding a vtuber covering tech/Linux stuff with what I think was also some text to speech software for the narration, and the TTS wasn't too bad either (if that's what it was).
Edit:
Huh, what's even more interesting about that video is the split-screen aspect of it almost makes it seem like you might view it in VR or something, but the visuals...Don't really make much sense for that.
That would make sense, and that's kind of what I have to think of it as, maybe as an ASMR thing? But it was a rather long video, and what I could see (not much) didn't seem to be focused on anything that could be described as fabric, like the noise was coming from off-screen.
