I think I had a lucid dream! My dreams have always felt a bit remote, or 3rd person, but this morning, I had a dream that felt like being in a movie, although I was not in control of the environment. The big thing is that it felt like I was making decisions about what to do next, at least more so, than other dreams where I felt like I was remotely watching myself. I think I was on a cruise ship picking out ties and walking around.
Despite my skeptical nature, I do believe in lucid dreams. For some time actually. When I was young, I had a few New-Age-ish beliefs about them, but as I've aged I've settled into a more logic-based belief system regarding the subject.
By most definitions, lucid dreaming does not require being "in control". The main aspect is "being aware" (of dreaming). In other words, your
conscious mind has to "awake up", at least enough to realize you're dreaming. The control aspect is optional. You can take full control, or sit back and let your
subconscious mind take over and handle things in auto-pilot mode. While taking full control can be fun and entertaining (and probably also therapeutic), leaving your subconscious in control allows for self-exploration and "getting to know thyself".
Of course, exploring "thyself" comes with the usual caveat. By doing so, we usually discover that "two players, one is light and one is dark" dwell in our subconscious realm. We encounter our ones hopes, dreams, and aspirations as well as our fears, worries, and inhibitions. But the journey can open a gateway to greater understanding of "thyself".
Unfortunately, many (most?) of the books on the subject of lucid dreaming seem to contain a good bit of pseudoscience malarkey. The only book I've found that comes close to adhering to the confines of science is
Exploring the World of Lucid Dreaming by Dr. Stephen LaBerge, a psychophysiologist. However, it too seems to get into some fuzzy-science areas.

If someone else knows of some good books or other source on the subject, hopefully they're see fit to post some info.
