Joe Loftus’s 2022 short Still Up There will creep inside your senses and linger far longer than you desire.
An astronaut on the brink of death regains consciousness in the vast emptiness of space. Disoriented and struggling to piece together how he got there, he is confronted by the sight of his own severed arm eerily floating past him — almost as if it’s waving. But is it really his arm?
Thanks for posting. Ended up watching the rest of his stuff, it’s pretty good. Not cosmic horror, but good. Sadly there’s not a ton of other videos he’s done.
