Once you realize you are dreaming, you become lucid, wheather you have any control or not. So, you had a lucid dream Congrats. Now you can check out some tutorials about control, but I would recommend first looking into stabilizing to make the dream last longer.

Since you have a moon for a dream sign, do reality check everytime you see it. You can even say 'next time I'm dreaming I look at the moon and realize I'm dreaming'. But this will only work, if you see the moon in your dreams often. If not, check out the sporadic awareness technique tutorial. If you don't have a dream journal, starting one will help you with remembering dreams. Happy dreams
