I've only had a few lucid dreams so far, in almost every case I have been entirely alone in the dream-world, although in one case I came across a man who I had never seen before, who very helpfully told me he was part of my subconscious. The thing I am wondering about is, when you meet someone in a lucid dream who is a person you know in real-life, to what extent do you actually feel you are conversing with this person, and not just some aspect of your mind? The reason I ask is because on the one occasion I conversed with a dream character in a lucid dream, I felt quite strongly aware that he wasn't real. I'm just wondering if it's like this when you meet people you actually know from real-life.
