He represents the symbol of justice in Diane's heart, and also appears in the dream as the incarnation of this part of Diane.
[The cowboy asked Adam if you agree with my point of view, attitude is everything. ]
She felt unconscious attitude is so serious, she should manage the heroine, but in reality they encounter because Adam is cynical C Camilla took the lead. As a cowboy in a dream, she uses authority to persecute Adam. On the one hand, she satisfies that she does not want Rita (C in the dream) to be the protagonist (reasons: 1. She has a better attitude, and neither A nor C have the attitude they should; 2. She wants C to stay with her all the time instead of being taken away by A). On the one hand, she should highlight her righteous voice. Whether it is a director or an actor, she should show his due attitude.
[Meet once and twice]
If you correct your attitude... if you do well, you have to see me again; if you do badly, you have to see me twice.
Who did he meet only once, and this role is very important as the key "driver"? Is the heroine. There may be a speculation that the cowboy is the incarnation of Diane in reality. So this paragraph is intertwined with reality. If he did not listen to the opinions in the dream and chose C, then in reality he would indeed meet D twice, an audition, and a dinner party. And if he listens to his opinions and does not choose C, then D will only have one audition to see him.
[Beauty, it's time to get up]
And D loves and hates C. In the dream, the cowboy shouts to get up to the rotten body, which is actually a dream version of the reality when D calls C to get up. At the same time, the image of the cowboy has a sense of justice in D's heart, so use this image to awaken oneself, the long dream should stop, and it is time to face reality. So the role switched back to the real image.
[Leaving of the cowboy in the final dinner]
At the dinner, when the prototype of C in the dream kisses the C in reality, D's heart is occupied by evil thoughts. She wants to get revenge. It is also at this time that the cowboy and the woman who kissed C got out of the dinner. When leaving, this scene left an impression on D, just to reflect the sense of justice in D's subconscious mind and leave, and the evil wish to kill C has surfaced. It can also be regarded as a part of the director's explanation of the connection between reality and dream. It may also be the subconscious reason that D in the dream chooses cowboy as the person who teaches A.
The above is just a little personal opinion.
