Yeah, everyone slips in and out of Lucidity during dreams. I'm still no pro at it, but I've finally gotten over that first initial excitement and I can usually stablize and keep lucid for awhile when I have an LD. I usually utilize the rubbing hands technique to keep me lucid and I remind myself every few minutes that I am dreaming. I try to always keep my hands rubbing and also to not get too wrapped up in the action around me.
