According to Loughner’s friend Bryce Tierney, the accused gunman was fascinated with lucid dreaming, in which the dreamer is aware of the dream. Loughner reportedly told Tierney, “when you realize you're dreaming, you can do anything, you can create anything."
Tierney said Loughner became more interested in his dreams than in reality.
"I'm so into it because I can create things and fly,” Loughner reportedly said. “I'm everything I'm not in this world."
Tierney said Loughner kept a detailed dream journal for more than a year, and in his alleged Youtube writings he mentions dreaming often, referring to himself as "a sleepwalker - who turns off the alarm clock."
