Hello, in dreaming, you're listening and interacting with characters without controlling them. When awake, you can make pretend voices in your mind but you have to tell them what to say, but in dreams you're easily a spectator is some complicated plot full of characters. What is "animating" them, and how can they be intelligent?

Oh, does anyone believe deceased relatives interact with us in dreams on occasion? I had some pretty real dreams in the past with my grandfather, but seperating real from fiction is probably a big mystery still.
