Very interesting
I used to keep a dream journal on a yahoo geocities site. Every night I could remember my dream, I'd write down as much of it as I could. Because I had no medium other than text to describe my dream, I'd occasioanlly change the color of the text to match whatever was the color in the dream at the time. It lasted a month before I forgot about it completely.
Your animation reminded me of it. And I'm glad I got to see someone do what I did, (basically describe a dream) but in a more visible form. If I had any flash talent I'd go about recreating the dreams I wrote down, because I purposely made sure to describe them as vividly as possible.
I liked it. I'm giving you high marks because you went and did something more for the reason of sharing the idea than anything else. Plus it was a decent animation. Keep it up. It was quite interesting.
