I'm not sure if I've mentioned this before but I once had a dream where an angry mob chased me down and beat me to death after trapping me in a dead end.
But it wasn't a nightmare. Seriously, no part of the dream felt scary to me, the only thought I seemed to have in the dream was that the death by mob was totally justified. "Well it was a fair court" could be the title of the dream.
I don't even know what it was that I had done to anger the crowd and no part of the dream actually had anything to reveal the reason. Apparently it wasn't important.
