Okay, I don't know if this works for others, and I know that n00b status diminishes the value of my opinion, b-u-u-u-u-u-u-u-t...

Basically, I talk about dreams all the time, as well as lucid dreaming, and thoughts in general. I also am very observant about small details. I personally believe these two things seem to initiate lucidity due to these subjects constantly rumbling in the subconscious. Since our dreams are typically surreal interpretations of our day-to-day experiences, the fact that that experience includes talking about dreams, makes think about them WHILE dreaming.
