New inspiration

Recently due to various happenings, I have fallen behind in my work, and so I am still on the stage where I am forming ideas.
I have decided to stick with the idea of atmospheric horror, and I am now looking at ways in which I can use the idea, and how different techniques in lighting, camerawork and sound effects can add to atmosphere.
I have found this video on YouTube.
It is an animation, which means I cannot directly take the style. It also doesn't have a story or dialogue, which are both needed in this project. However, the lighting in this is very good, and the music is effective. The jumping transitions and use of surreal props also serve to unnerve the viewer. I will definitely look into how I can create similar lighting, and, if possible, find similar sound effects, particularly the high-pitched scraping/squeaking noise.
