Hi Kathy. What if you take the concept of what you have seen and use it as a stimulus for something creative and original? Since you can't stop thinking about it, use it to your advantage. Literally take a sheet of paper and brainstorm some interesting ways you can incorporate this image into a new piece of artwork that you can call your own. If for example, the image you have in your mind is of a particular face, take that face (or a similar face) and draw it with a new body, with new clothes, in a new environment that tells an intriguing story.
