I’m trying to remember the name of an old horror movie (90s or 80s but might be from the early 20s too) I watched as a kid. I don’t recall much, but there are two specific scenes that stood out to me:
1. A group of friends is camping in the middle of nowhere (they might get lost too but either way they spent the night outside) when they discover an old, abandoned cabine. Unknown to them, a killer is living there, and at one point, he spies on them through a hole in the floor and only his iris is visible for how tiny that hole is (he was hiding in the basement
2. In another scene, a couple went outside to lay on the grass. When the man leaves briefly, the killer appears and brutally twists the girl’s body. (They didn’t show when the killer came in and when the bf is back, he puts his hand on the girl’s hips and gets shocked to her back being in the front)
The movie revolves around a single killer who was born deformed and abandoned by his mother in the house where he now lives (not sure about this part but surely he’s deformed)
