Psychologically, does my nightmare signify anything?

Look at the dream from this perspective...every EVERY character in the dream is YOU, no one else...but different facets of your personality. You attach others faces to these facets, but they are you. In analysis, you would find that this is no more than your brain playing games while you sleep...playing bits and pieces of movies, of stories, etc. you have heard/seen, stitching them together to form one silly "story" that makes no sense. But your brain had fun. ! GW
