I experience these images, as well. I don't know why I have them or what they mean, but I let them guide me in what I choose to paint. Also, when I approach my easel holding a blank canvas, I am inundated with transforming images seen through my third eye. I find it quite enjoyable. In fact, my wife has a difficult time convincing me to leave my studio sometimes. It's rather addictive.
My opinion is for you to just milk this experience for all it's worth.
