Logic in dreams

When I first read about lucid dreaming, I was told that a lucid dream is far more logical and less sporadic than a traditional non-LD. After keeping a dream journal or some time I have come to the conclusion that almost ALL of my dreams are physically possible in the "real" world (with the exception of one wherein the inside of a window was 60+ miles away from the outside).

I then make the assumption that this means my dreams are overly logical which leads to my question...

Are logical dreams indicative of either
A. I'm slowly approaching the threshold of lucidity?
OR
B. My waking fascination with science and logical explanations is soaking into my dream world?

I have found that a form of logic always applies to dreams. If you are highly logical, I would expect that to feed through to your normal dreams.

Dreams are a reflection of ones own subconscious. So, like "My Other Brain" said, if you are a very logical person, then your dreams can end up very logical. Personally, my dreams are very random and crazy. A direct reflection of my own mind, random and crazy (the good kind of crazy, lol).
