Needless to say, the part with the dancer being controlled and then transformed into something else totally freaked me out, mostly because I’ve had nightmares like that.
And then, of course, you have the tentacles and the graffiti, which feels like something that H.P. Lovecraft would have come up with if he had lived in New York City in the 1970s and had to travel on the subway everyday. It’s easy to imagine old Howard Lovecraft, heading to an accounting job while staring at the graffiti all around him and wondering what type of monster was responsible for it. Cthulhu tags his territory.
As for the wizard with the eyes — well, glowing eyes are always freaky.
