I think the first step to really getting things set in place to find answers, is awareness. Practice being aware as often as you can while lucid and it will make you sure of your abilities and also increase focus as well as the duration of the dream. Once you've done this and really set the stage in your lucid dreams, I would then search for your answers. Remember, there is a lot of symbolism in dreams and just because you don't understand something at the given moment doesn't mean that it won't "click" later. And yes, try more specific questions. You'll get some interesting answers for sure.

Another thing, I don't think you've experienced a stroke of luck, that really doesn't happen too much with lucid dreaming. I think your results has had a lot to do with your meditation.

That's just my two cents,
