When I was much younger, I had a dream where when I was waking up I heard a voice in my head asking if I wouldn't mind giving him a lift. My response was "Sorry, I don't pick up hitch-hikers in my head." Then I woke up a bit, and forced myself back to sleep so that i could say "Sorry, though. I hope someone stops for you."

I told a friend and he said that its a good sign if you are polite to parts of your psyche. They have a reality, even if they are only really synapses in your head. Dreams allow you to practice virtues and learn lessons. Both I find easier if I treat dreams as real to some extent.

Of course, sometimes I don't do this.
