Unis, Use one of the kick start techniques for Image Streaming. Also it starts out being like remembering a picture of your car. You describe it as best you can. Very rarely do the images appear vivid like when you are at a deep level in meditation.
If for example you just momentarily thought of a flower describe the flower you might name the it and then go on to explain what colour it was, how open it was how healthy it was. Any flash that makes you think of something is the basis of your image stream. The image may already be gone when you start streaming so describe what you remember in as much detail as you can. It gets easier.
