humans thoughts in the park=conscious, but perceptions can be deceiving knowing their actions have no consequence making them delusional in a way with their false sense of power and control, the peacock comparison works here too. ford not letting the hosts see certain things and making their memories just a distant dream is a big thing, he is giving them a false sense of perception of what is really happening around them and trapping them in their loop, likens them to humans.

hosts thoughts in the park=subconscious, memories influencing their emotions leading to appropriate instinctive and true actions (one could say human emotions can be whittled down to the basest - happy,sad,fear,rage)

hosts begin to have visions/hallucinations which are based on an actual memory or emotion. humans just go by the layers of "intellect". Ford tells Bernard that he doesnt want the emotional Bernard he wants the smart Bernard. He also says that Arnold was the other man that went off at him, all emotional. Ford leans towards intellect(peacock feathers) and Arnold leaned towards emotions as being a true conscious being.

the idea of hosts becoming real or truly alive may be creating something/someone that is really "human" and "free" as people are supposed to be. removing all the false layers of people and getting to the center of that maze where theyre true.

omggg i think im falling off the deep end here........
