I think I also found my DG... I often feel his presence in my dreams - of someone familiar but unidentified. Before joining DV I didn't even know something like that existed. I haven't really talked to him yet or even clearly seen him, as I just had my first LD. But he is there to help me in my dreams, sometimes by just being close by giving me confidence, sometimes by asking things of me that I can't do in real life.
I see him as my support by exploring my dreamworld and learning new things in it. But what the others said sounds interesting and so I am looking forward to getting to know him better.
