Well i have a similar problem to yours. my dreams have been soooo real lately and i usually realize its a dream because its so real. and everytime i get lucid, i forget about being lucid a few minutes or seconds later. you probably know about how to keep the dream from ending right? well i first use dream spinning(it changes the surroundings around you) where i just spin around in a circle while i am floating, keep thinking its a dream, and then after i am done spinning i hold my hands in front of my face and just walk around looking at my hands and thinking its a dream. for me, looking at my hands stabilizes my dream and keeps me lucid for a while. since i cant lucid dream at the moment for some reason, i cant test anything about how to remain lucid, i would need someone's help and advice here, or someone that is willing to try sharing dreams.
