Think of the movie "Inception." Some Lucid dreamers believe they have superhuman powers and can defy the laws of gravity and society without consequences. An expert on the show seemed to imply that it's possible Loughner thought he was dreaming when he committed the shootings.
Given the alleged pre-meditation, his acts don't appear to have been spontaneous -- as in sleep-walking. Could he have planned to test his ability to direct himself to engage in the shootings during an induced lucid dream? Did he believe he was only real when he was having an induced dream? Did he believe he could wake himself up after the shootings and they would turn out to be just a dream? It will be interesting to learn what the doctors who evaluate him have to say about this.
Loughner was considered pretty normal by those who knew him until 2006 when he dropped out of high school after his junior year. That's when he started to change. That's when he became obsessed with lucid dreaming. As Loughner's interest in dream life grew, his interest in reality decreased.
According to a female friend who was interviewed on the show, it was during this time, in 2007, that he met Rep. Giffords, and asked her the question. "What is Government if words have no meaning." When Rep. Giffords didn't give him a satisfactory answer, he decided she was a fake, and his grudge against her began.
Nightline then showed Mark Chapman being interviewed in prison in 1992 by Barbara Walters. In discussing why he killed John Lennon, he tells her he had decided John Lennon was a phony.
Another expert on the show (who was not particularly impressive to me as he dogmatically lumped all lone shooters together to say they were all motivated by a desire for fame, and in every case their actions were an attempt to steal it from someone the public found deserving of it) said that in his opinion, political discourse in this country had nothing to do with Loughner's actions and that John Lennon probably had more to do it than Sarah Palin. I agree with his conclusion, but not his reasoning. I don't see anything to suggest Loughner wanted to be famous. It makes more sense that lucid dreaming and his perceived fakeness of Rep. Giffords played the predominant role.
While Loughner incoherently ranted against the Government, his friends say he was most interested in things like Mayan prophecies that the world was going to end in 2007. He was a registered independent and didn't vote in 2010. No one can agree on whether he has an ideology, what it is, or whether he identified with the right or the left. At most, he seems to be a conspiracy theorist. He may have descended too far into the recesses of his pretend world to care about traditional politics at all by the time of the shootings.
The point is, the key to understanding Loughner's actions, if possible at all, is going to be found in understanding the nature of his mental illness. All the self-serving political discourse talk being engaged in by both sides of the political spectrum is both boring and a waste of time.
That said, I'm not finding lucid dreaming all that exciting a topic. But then, I also had a hard time following the movie "Inception." I'm not sure why, because I found the subject of "Dreamtime" fascinating -- at least as it was portrayed in Peter Weir's 1977 movie "The Last Wave", which explored the Aboriginal belief that there are two worlds and two forms of time. The movie was about a white corporate lawyer assigned to represent four Aboriginal defendants in a murder case.
Plagued by recurring bizarre dreams, the lawyer begins to sense an "otherworldly" connection to one of the accused. He also feels connected to the increasingly strange weather phenomena besetting the city. His dreams intensify along with his obsession with the murder case (which he comes to believe is an Aboriginal tribal killing by curse, in which the victim believed). Learning more about Aboriginal practices and the concept of Dreamtime as a parallel world of existence, the lawyer comes to believe the strange weather bodes of a coming apocalypse.
From the movie:
"Aboriginals believe in two forms of time; two parallel streams of activity. One is the daily objective activity, the other is an infinite spiritual cycle called the 'dreamtime', more real than reality itself. Whatever happens in the dreamtime establishes the values, symbols, and laws of Aboriginal society. It was believed that some people of unusual spiritual powers had contact with the dreamtime."
Maybe it's that Lucid Dreaming seems overly egotistical, compared to Dreamtime. Or maybe I'll just have to watch "Inception" again. At least it will be more interesting (and relevant) than the endless speculating about the tone of political discourse in the country.
