[Movie/TV][~2010s] Scene with a white human silhouette on a white background bleeding from the mouth

​I am looking for a specific scene from a movie or TV show that I saw on TV about 8 years ago (around 2017).
​Here are the details:
​I briefly left the room and when I came back, the screen was completely white.
​In the top-left corner, there was a white human silhouette.
​The silhouette was barely visible against the white background; I could only distinguish it because it was moving very slightly.
​The most distinct feature was blood flowing from its mouth.
​The blood was dripping down almost to the bottom of the screen.
​Since I missed the context, I don't know if this was a dream sequence, an intro, or an artistic ending. Does this ring a bell for anyone?
