I discovered lucid dreaming while reading a meditation book, but for some time i thought it was just a joke from a happy and cheerfull buddhist monk.
Soon, it became obvious to me the infinite potential of lucid dreaming.

" You can even meditate while sleeping or dreaming.As you fall asleep, you can either rest your mind in objectless meditation or gently rest your attention on the feeling of sleepiness.Alternatively, you can create an oportunity to turn your dreams into meditation experiences by reciting silently to yourself several times as you fall asleep, I will recognize my dreams,I will recognize my dreams,I will recognize my dreams.
