Rainbow,
I think that Reiki does help us to be more creative. I think it is because we normally have all the negative stuff we deal with, anger, disapointment, guilt, and so on. Reiki brings it up to deal with and clear. As we clear it out, all the creativity that has been there all along can now show up.
It is like going to a movie theater and as the movie starts, the curtain is still across the screen. You can see the movie, and you may even think it is ok for a little while. But when the curtain is pulled back, you can see much clearer the colors and the people and the story. We are kind of like that when we don't clear out the negative energy, it is like that curtain. When Reiki, or anything positive helps us to see better, the colors are much more clear, and I believe we become more creative and more intuitive!!
Love, and truth, Priestess
