glitch in the movie

Rating: 10/10 (8 January 2006)

I loved this movie.
And in great movies there are usually some plot holes you have to deal with.
The one question I have for this movie, other than the obvious psychological questions that it fills me with, is if Julie was such a deranged character in his life, why didn't he just not include her in his lucid dream?
Or was that part of the glitch. I figured the glitch was that it turned into a nightmare.
The glitch wasn't necessarily explained enough in the movie. All that was said was that his lucid dream turned into a nightmare.
