From the third-person perspective, you might be in the position to direct the actions of yourself and those other images of people in your dreams. Have you or someone approach this person and ask them who they are and what they're doing there. By initiating the approach, you may be able to interrupt the typical flow of the dream. When prompted by that other voice, say, "No, I'm staying asleep!" and come right up to this man. Who knows, maybe he has information that you can use.
