Man I love ancient egypt. There is so much potential for mystery. I can't help you but this is really fascinating. Try to remember just a few symbols in the grid each time it happens and then gradually complete an image of the drawing.

I have never experienced the after image effect you speak of. What is that like?

Also.. It would be nice to know what ancient egypt means to you. If you've spent a lot of time wondering about it before this started happening etc.
