A lucid dreamer is a person who is aware that he or she is dreaming and is able to manipulate the plot and outcome of the dream, like a video game. It is not uncommon, and in children it can happen frequently, even as an expression of creativity, said Gary Schwartz, professor of psychology and neurology at the University of Arizona.
It appears that Jared Loughner, allegedly responsible for the shooting at a supermarket in Tucson, Arizona, on Saturday, took a keen interest in the phenomenon. In the YouTube video called My Final Thoughts: Jared Lee Loughner! that is said to belong to him, he talks about conscious dreaming and reflects a blurring between waking life and reality — “Jared Loughner is conscience (sic) dreaming at this moment / Thus, Jared Loughner is asleep,” he writes.
