Amityville II (1982) Sonny Gets Possessed
Part of the Sonny gets possessed sequence in "Amityville II: The Possession" from 1982. The end part of the scene can already be found on YouTube, but I really like the camerawork and some of the weird yet understated scares in this part like the arm coming out of the wall. Also the way it keeps putting us in the perspective of the evil spirit and breaking the 4th wall by having Sonny stare and even shoot at us.
