Has anyone successfully envisioned a dream character they would like to use in their dream?

I would like to create my own dream guide type character, someone who I would meet quite often in my dreams whenever I need a partner. I can pretty much totally envision her, from her appearance to her personality, but has anyone been successful in putting such a character into a dream?


I'm going to try it the next time I become lucid, but so far I haven't been able to create people, only objects.
