This is one thing that will always work if you try it. you know how sometimes, you see people in your dream that live far away? like, maybe your aunt lives in another state? or a friend. the way i had my first lucid dream, is because i moved to another state. i was back in my hometown hanging out with friends when i told myself i dont live near them anymore. made a few reality checks and it worked.. just ask yourself whenever you see someone or talk to someone what their names are and where they live. maybe you'll do it in your dreams and attain ludicity. hope it helps!
