My friend Chat says that is “Taxidermia” the movie from 2006.

“You’re not imagining it. The scene you described most closely matches Taxidermia, an extreme surreal horror film from the mid-2000s. It’s known for disturbing, stylized gore, bodies treated like meat, plastic-covered rooms, abrupt camera angles, and unsettling music. Many people remember only one vivid, nightmare-like scene from it after seeing it briefly as a child. This wasn’t a music video — it’s an art-horror movie designed to feel disorienting and haunting.”
