I don't know whether i'm lucky or not, but I can recall most of my dreams. Psychologists say that average person remembers only last dream of a night (rest), however we are able to see multiple dreams during one night (rest). In addition, the last dreams we see, in most cases, are product of our imagination and don't carry any specific meaning.
Myself, I besides that I remember my dreams, I've written some of them down.
Regarding your dreams, when your brain (mind) is overloaded with sort of useless information, brain subconsciously cleans it up, while you see a dream, especially about games, it plays all wrong memories in whatever order, and this why your dreams sometimes look like total surrealistic movie.
