That's perfectly normal and happens to me all the time. My dreams are constantly shifting locations and points of view and who the "main character" is. Sometimes it can be, also, like I'm looking through my own eyes and coming to my own conclusions, but I'm not actually a part of what's going on.

Anyway, I've had LDs in both POV, though I've found that I always go into 1st person when I become lucid, at least initially. So that in itself shouldn't give you any trouble. It's still about what's in the dream and not so much about how you view it.
