Help Finding Specific SSS Short

Hi, all! Hope you’re well. This is my first time posting on here, so thanks for witnessing a new Redditor making their first post :]

I was wondering if any of you remembered the episode where Cory watched a horror short film that really stuck with me. I’d really like to find it, as I know for sure that I watched it at some point. For context, the short was a live-action one and it featured a woman waking up in the middle of something I can only describe as a granite slope. There was an abyss down below and the main character woke up in a very awkward, uncomfortable position. The film followed the woman’s attempt at escaping, which was ultimately a failure. The woman was laying down, but that her foot was tucked behind her thigh, almost touching her back. She tried climbing the granite slope, but it was so coarse that her palms ended up bleeding.

Anyway, that’s all I remember for now. Anything helps! Thanks so much, everyone :3
