Well then, my own "experiences" have shown me that my dreams are irrelevant and meaningless.
To prove the point I abstained from tv, games and books and after a certain length of time I noticed my dreams became more and more mundane and disjointed. All that supposed meaning I made myself think it had just went "poof".
But then again herein lies another little tidbit, all the stuff we expose ourselves to affect our dreams to a massive degree. Perhaps if one was to discern any actual meaning from a dream then maybe one needs to attain a great degree of detachment, observe the dream without judging and without expectations or assumptions.
