Watching the Star Trek: Voyager episode gave me lots of thoughts about avoiding reality, day dreams and having a vision. Reading Nothing Holy about It: The Zen of Being Just Who You AreBurkett talks about Man's Search for Meaning, and how people who could think about life after the camps were the ones who survived. I've also read Daydreaming : Unlock the Creative Power of Your Mind. The thing is to be mindful about what it is and not take it for what it's not. In the dream only the dream.
In the episode the doctor loses track of reality, and that is a problem. I think a lot about the reality principle in conflict with the pleasure (or avoidance of pain) principle. He's embarassed by his desire to be more regarded, loved, respected.
