To correct you, being one's lucid when one's aware that he's dreaming, control is completely separate from that and there can be non-lucid dreams with levels of control.
As for the dream experience, haven't had this particular experience, but dream characters can be surprising sometimes indeed, maybe something shared dreaming related was on your mind recently and subconscious decided to add this into the dream that way? If anything, i believe into possibility of shared dreaming, since everything in dream is possible, if you are interested in it, check out the Beyond Dreaming section, there are some threads about that, and http://www.dreamviews.com/internatio...aming-project/ too.
