My dreams, for the most part, are in first person. Every now and then, I will get a scene or a certain cinematic shot that will change my vision into 3rd person, but it doesn't happen all that often.
A funny thing I just thought about though was that normally, when I dream, I feel like I'm always myself. Only when it's blatantly obvious that I'm someone else (like if I'm Batman or Superman and I can see that I have their costumes on and stuff) do I ever get the feeling that I'm not me, and that doesn't happen a lot. I had a dream last night, though, that I was someone completely different and the only reason I found that out was because I saw a picture of "me" that wasn't me, and I looked in the mirror and saw that I wasn't myself...
...my point is that...I wonder how may of the dreams that I have where I think I'm portraying some "alternate universe" version of myself...when I'm actually someone else?

...hmm...
