Lucid dreams, etc.

The other morning in the shower I was reflecting on a dream I had the night before where a friend from high school made a cameo. The dream, like most I have, was pretty random, so the storyline won't be the focus here.

What really stuck with me was the thought of how many people's dreams I've made an appearance in. And why? Then I took the thought a little deeper. How many people who have passed me on the street, in the hallway, or on the road have had a dream with me in it? Then what really freaked my shiz was the possibility of being in people's dreams whom I've never met where I was, for example, just a random face in the crowd with no central role, a dream extra, so to speak that the dreamer never knew was there.

Along these same lines, I started thinking about my ability to sometimes control dreams and events in dreams, did a little research a la google, and found out that these dreams are categorized as lucid dreams. Apparently, not everyone has the ability to control their dreams while others don't know anything but. I'm sort of somewhere in the middle. What is most frustrating, however, is when I am fully aware during my dream that I'm trying to control my dream and can't for whatever reason. That's when I seem to always wake up. I suppose it's the frustration that wakes me up.
