Is it possible that the DCs we see in our dreams are actually real people in thier dream bodies?

I started thinking about this because just last week I had two LDs and there were huge amounts of people. One was in a casino/neighbors house and the other was in a mall type office building. I'm talking a lot of people. They were all rushing around and I didn't have much contact with them. I used these two environments as a training ground for my LD. After waking I began to think that with the millions upon millions of people in the world, is it possible that we ever cross each other in dreams??? I know this has been discussed but now it seems that it could be true. The people I saw were faces I did not recognize and they were all moving together so fast, like in thier own worlds. I also thought that since I was in a lucid which is another level of dreaming, perhaps you can connect with people on another level..... I don't know just some food for thought.
