American Dream?

Back in the day when I was taking full-time French training they kept telling us that we'd know when the French was taking when we started dreaming in French. Well, I dreamt in French but still didn't pass the final oral exam. Oh well.

My question is, if dreaming in French is a sign that you've learned the language, can you assume you're Americanized when the money in your dreams is all green? And don't give me any of that "people dream in black and white" nonsense. I dream in color all the time.
