I dream in 3rd person almost all the time. My dreams are usually like movies, where the camera moves around to wherever it needs to be. Often times I control myself, but I rarely see what's going on from my own perspective. I had a talk about this with someone at work once, and she said she always dreams in the first person, and I found that odd.
Very rarely do I ever have control of someone other then myself if at all, but my mind has ways to get around this basically. My dreams rarely consist of people I actually know well. They're full of aquantances, so that I can imprint how I think they'd behave in whatever situation onto them. I'm guessing this is to create a movie like effect, because my mind doesn't want people to be included wherein I would know their reaction to certain circumstances.
My dreams are also usually pretty uneventful... with fairly average things happening but with one slight exaduration that makes things odd. Occasionally though, I have crazy awesome dreams that would make fantastic actual movies.
Also, I often lucid dream, and therefore can control many things within it often times. I only ever dream after I have woken up and then gone back to bed. It's more fun this way anyway lol.
