Welcome to DV, Norvii!

Noticing strange things in your dreams is a good sign. I think what you need to get you lucid is a little bit of awareness training to raise your awareness. Check out the SAT and http://www.dreamviews.com/f49/all-da...gyoshi-113253/ tutorials.
Try to add more RCs, like the looking at hands, thumb through palm are really good, also the nose pinch you already doing.
Try not to rely on reminders like writing on hands, because if you don't see them in your dream, you will loose the opportunity to become lucid. You see, you do the RC only after you become lucid. And you will become lucid because of the awareness training.
If you can't focus on a dream that you would like to have, no worries, you can change the scene after you become lucid.
Oh, and your English is perfect Please ask, if I didn't answer some of your question. Happy dreams
