1) Yes, how you view waking life can affect how they look in dreams. Dreams are based off of your waking life anyway. Also not all dreams are very vivid and not all lucids are very vivid either. I remember a few LDs of mine that were so faded and poor quality I could barely make out my door. All I did after that was yell, "Clarity!" and the dream became clearer. That's the beauty of lucid dreams, you can make them more clear via dream control whereas normal dreams are random, sometimes very clear and other times hazy and foggy.

2) As long as you were repeating to yourself that you were lucid it probably wouldn't change back into a normal dream. Your arrogance in the dream is understandable, you are essentially god and can do whatever you want so you're bound to have some arrogance in it. However you can keep this in check with good self-control.

3) A lucid dream, by definition, is a dream in which you are aware that you a dreaming. If you consciously acknowledge the fact that you are in a dream then it is a lucid dream. However, you can subconsciously say, "I'm dreaming," or, "this is a dream," and not realize it, like when you're rambling on about something and not realizing what you're saying. This is combated by making sure you truly question reality during RCs and ADA, otherwise the half-assed attitude you give them in waking life will transfer over into your dreams and you won't get lucid.

Hope this helps and if you think I mis-read or mis-understood any of the questions just say so .
