I haven't recieved my course. I don't know that the dot sterogram is that you're talking about. And yet, I have advice. Some people just have the gift. *LOL*
I'm betting that if you try and focus beyond the picture (dot stereogram) then you'll have the image come together. You can get this to happen quickly if you practice moving your focus to the paper surface to beyond it. This will help you learn the muscle control to meet this new desire (you don't normally need to focus beyond the surface of what you're interested in).
I'll say that the first few times you get the image, try and hold onto it as long as you can.
