I saw a part of this movie. It was an artistic movie, it looked like it shouldn't have been a movie, but it was. There was a girl, the protagonist, dressed in a green long dress, assisting a gala with her family. She pretended she liked the play that they were watching from a very fancy round table, and she smiled when people watched her, trying to please everyone in her family.
However, she excused herself to go to the bathroom. On the way to the bathroom, she started making weird faces, and dancing frantically, fighting the demons that made her conform to society. She found a tall black man, who she attacked artistically and dismayed him. She was looking at the camera most of the time while she was dancing, and she could shoot projectiles out of her hands, like small lightning bolts.
EDIT: Since the original video was shut down, I re-created it. I hope you enjoy it (and I also hope they don't copyright strike me...
