Okay, so this film is from either the 60s or the 80s or in between.
the only thing i remember about this film is that its very hardcore avant-garde, its animated in 2d, its black and white. it also has a unique idea of repeating each scenes multiple times, because the animation is relatively short, and the details are much.
one scene i remember, is a father holding a child, the child looks at the father, all normal, but when the child looks away, the father’s head becomes something horrid, like a fast blur of nightmares, and then when the child looks back at him it goes back to a normal face. then it repeats itself.
the animator who drew this i think has several films. i just can’t remember how i got to him even.
