Yes by me they seem ghost like sometimes too. To check if you're crossing your eyes have a look at some stereograms.
We are aiming for parallel vision http://www.vision3d.com/3views.html excellent diagrams here.
Tips for ways to see them are at the bottom of that page.
If you're looking for a site with stereograms this one has a decent collection at a nice size. http://www.eyetricks.com/3dstereo.htm
If viewing them on screen is difficult print some out.
Number one rule for photoreading... play with it. Use a relaxed gaze and if you cannot see the blip page use the X technique. It works just as well and using that consistently you'll probably gain a steady blip page a lot sooner. In fact if you find yourself crossing your eyes, I recommend you leave the blip page for a while and concentrate on just relaxing your gaze so that you have a soft focus with a broad peripheral vision so that you can notice both pages at once.
