1) Sometimes lucid dreams can be spontaneous. You may be aware enough in your dream that you notice something that's out of place, or you might feel like you're in a dream. But lucid dreams aren't always induced by actively trying techniques.

2) I wouldn't say your lucid dream was big or small, it was just lucid. However, I seem enjoy this type of lucid dream, when I wake up after the dream and remember it all, more than lucid dreams which I don't recall until later in the day, because it feels like I've actually been living the dream, and I feel like I've slept better.

If you've got any other questions, or need clarification on my answers, feel free to post, or send me a private message.
