Some dreams are like re-runs. They play a plot in your head that you've already seen before. And depending on whether you liked them last time, or whether you finished it last time or not, you may decide to stick around and 'watch' that dream again. I had a similar dream a few days ago, one of my last nights in Canada.
I don't know why but it felt like I have been a part of this plot before. Either I did not know how it ended or I was just enjoying it a little too much; hence, I stuck around. It ended with somebody getting shot. I, without even thinking about it for a second, 'walked out' of the 'theatre'. Was it my conscience that had just died? How could I not feel anything for a person that had just died? For the person I probably killed? Twice?
