You know, the one with the dog vivisection: I always wondered, in a movie where everything can be explained, why are there sliced dogs (half alive no less!) in a mental hospital that people "weren't supposed to see". It was not a dream, like the swan from the painting was. Sure, it adds a nice gory shock to this strange and wonderful Giallo, but did it mean anything? Did I miss something? I've seen enough Italian films to know that not everything you see has a meaning or is logical. Mostly it's just the opposite. But in this quite serious Giallo this scene stands out and, to me, adds nothing to the story.
