TUCSON, Ariz., Jan. 11, 2011— -- When Jared Lee Loughner allegedly pulled the trigger outside a Tucson Safeway Saturday morning, killing six people and injuring 14 others, is it possible that he thought he was dreaming?
Friends of the suspect Jared Lee Loughner, 22, describe him as being obsessed with dreaming.
"I am a sleepwalker -- who turns off the alarm clock," Loughner wrote in one video.

According to friends, Loughner was particularly interested in something called lucid dreaming, when people try to take control of their own dreams to manipulate them.
"Lucid dreaming is when a person has not only very vivid dreams, very clear dreams, but they are consciously aware that they are dreaming, and they are able to influence the dreams," said Dr. Gary Schwartz, a professor of psychology and neurology at the University of Arizona.
It's a concept straight out of movies like "The Matrix" and last summer's "Inception," in which characters live out superhuman lives in their sleep.
Stephen Lebarge, founder of the Lucidity Institute, holds dream camps in Hawaii where he trains people in lucid dreaming, helping them to literally live their dreams.
The dream is "the place where you can do anything without external consequences. So it's a place you can safely explore how to live, what to do, what you might want to do," said Lebarge.
According to Lebarge, the first thing many people want to do in lucid dreaming is to violate the laws of physics -- flying like Superman, for instance. The next thing many want to do is break the rules of society, testing taboos of sexuality and even morality without fear of consequences.
But Lebarge says lucid dreamers can also master martial arts, speak in foreign languages, transport themselves anywhere in the world -- living dream lives without limits that seem every bit as real as their waking lives.
Bryce Tierney, a friend of Loughner's, told Mother Jones magazine that the alleged shooter kept a journal of his dreams, and Tierney saw it.
"That's the golden piece of evidence," Tierney told the magazine. "You want to know what goes on in Jared Loughner's mind, there's a dream journal that will tell you everything."
