Last night i had a lucid, but then my dream started to fad so, then i started rubbing my hands together and that prolonged the dream for about 5 or 10 minutes. But then i felt my eyes opening i tried to close them but they opened all the way and the dream was over. How long should i rub my hands together to prolong my lucids? Are there other techniques besides spinning (which the last time i did it just changed dream scenes) that prolongs lucid dreams? And why does rubbing your hands prolong lucid dreams?
