Is There a Horror Elements in the Movie?

The first images of the movie, we see the lighting in there's so red. I don't know if there was a deeper meaning to that, but who knows?

Ok, so i have an idea is that she, like, that's telling the audience that she doesn't feel comfortable. And it's only revealed later, y can.
