I've done some reading but it's been a while. Honestly my dreams are filled with so much junk they don't seem worth the trouble to interpret. I remember somewhere reading that we impose a narrative on random images after we've woken up, which sounds plausible. I've also experienced "lucid dreaming." Richard Feynmann has a great take on that. It has been psychologically useful on a couple of occasions. The dream being, I am in great fear, I am hiding from an intruder, or some such. Then I realize I'm dreaming and confront the intruder - get the *&$% out of my house! And wake feeling empowered. What it all MEANS - jeez. Anyway it's an odd manifestation of mind to me, and prolific.
That you are rejecting an idea or thought (MEME VIRUS) that is trying to assert itself in (infect) your mind.....
