I would like to point you to this well written thread as well. The Master Key
Your second and third point could just plant the idea even stronger in your mind that lucid dreams have problems you need to fix. Forming a mindset like that is not good. If you expect to use a trick to fix things, lucid dreams will start having more things to fix. Find the root of the problem and correct it, instead of trusting a “trick” to fix things. Lucid dream seems blurry? Is it possible there’s something in your eyes? No. In a dream you are not using eyes at all, it’s not possible for something to hinder your sight. Fully realizing and believing this will fix the blurry dream and it’s a healthier mindset to form.
