I voted "an equal split", but for me it's more like it's in second person. I'll be making my own choices, but I'll see myself from the point of view of the person I'm talking to/interacting with. It's really weird and I don't know of anyone else who has dreams like that (other than 46odnetnin, now that I've read their post). As for how vivid my dreams are, the center of attention tends to be pretty clear, but anything else like the setting and background activity are usually quite blurry. Smell and taste doesn't even occur to me so it's just sight and sound.
