Need some solid cranial movie recommendations

Hey guys, I’m bored and need to add some more films to my list. I’m into deep thought provoking films that leave me with lots of unanswered questions that drive me crazy. Here are some of my faves at the moment though I know not all of these fit the description above but yeah. Any recommendations are appreciated. And if there’s any of these films below that you haven’t seen I would highly suggest checking them out.

The lobster The killing of a sacred deer Requiem for a dream Lars and the real girl Eternal sunshine of the spotless mind The machinist Triangle
