Have you ever seen Begotten, LDS?
Begotten (1990) - IMDb
Judging by your comments about that youtube, you'd probably appreciate it (I purposefully didn't say 'enjoy' or 'like'). I watched it about 10 years ago with an ex who rented it because shed just discovered netflix and somehow it got recommended by them. I was eating dinner when she put it on and I completely lost my appetite. It's probably the most disturbing movie I've ever seen.
