If you are to get a hint from your subconsciousness, to find an intuitive solution for the situation you have in life, to make a choice or to look beyond the event horizon into you possible future, it is not a lucid dream you need. As soon as you perceive yourself in a dream, you will control every aspect of it and create a world inside a dream, but it will have nothing to do with reality. Moreover, I would say it will be one more illusion which you probably have long time avoided in real life.
Even logics and analytics of your perceived ego will be not a help but an obstacle for you in a dream. You can speak with your subconsciousness only with your rational mind turned off. You have enough of it in your everyday life, anyway.
