The Shower Scene questions

there was 35 shots
I think Alfred Hitchcock used so many quick shots to make the scene more dramatic. The scene was a very suspenseful because of the way he used the audio, the shots, and the speed/motion.
Alfred Hitchcock probably chose to show the shots like that because the motion and the angles he used made the film look more dramatic and it matched the idea of the film. So the shots and the purpose of it both matched.
The juxtapose shots make the shots seem more than what they are. It makes all the shots seem breathtaking and the audience will be shook at how scary the shots look.
