If you take a look at the backdrop of the stage, you would realize that there are two pillars with an arc, this is a form of symbolism used in freemasonry as shown on the right. Lady Gaga appears to be down on the floor due to the fact that she was hit by a fallen chandelier and she is being attended to by men wearing white underwear over their faces. The dancers in white seem to be playing the part of doctors attending to the fallen Gaga. She is dressed as a white rabbit showing that she is in an altered state of consciousness also explaining why the image of the doctors are altered using underwear (a sexual symbol) and not masks. Later we see the two men guiding Lady gaga to a spiral staircase between two pillars, where she undergoes a transformation or rebirth shown by the removal of her mask and cape. The second degree in freemasonry is The Fellow Craft Degree, the winding staircase is the symbol of this degree. Winding staircases along with ladders, vertical ropes and mountains symbolize advancement and ascending to new heights. Emphasis can be placed on Lady Gaga's right arm which is sleeveless and naked while her left is covered. This illustrates part of the induction into The Fellow Craft Degree where the right arm has to be exposed.
Later in the performance when she gets to the line " We're plastic but we'll still have fun" you will notice her at the piano and she enters into a state of "distubia" then she gets up and blood begins to flow. At this point it really doesn't take a genius to see that this is of occult origin. Lady Gaga is wearing white so this demonstrates a virgin sacrifice for fame. Then as she is hung up and sacrificed a gateway opens under the royal arc and light emerges from it. As stated before vertical ropes are a sign of advancement, therefore we may conclude that Lady Gaga was served as a sacrifice for advancement in fame.
