RPG and Lucid Dreaming

Hi, I'm a huge fan of role-playing/RPGs, particularly the forum kind where you play as any sort of character you can think of and write out posts with other players as that particular character you've chosen for yourself. I was wondering if in lucid dreams I can make my dream-world characters think I am a character/alter ego of sorts? Don't go telling me about split personalities and stuff, I know not to get to obsessed about dreaming and whatnot. I'm just wondering if it is possible to make worlds in your dreams where the characters think you are a character of that world while you in that dreamscape?

in a lucid dream, anything is possible so yes. im sure people on the forum have done this (i would have but im not too great at getting lucid), and shouldnt be to hard for you to do, have fun.
