Casting boards.

A while ago I dreamt about a board that had the earths elements on it and the group of females I was with were all taking turns tossing crystals on this board. I got some information in the dream as to what it means if you land on certain elements.

Now, I never heard of anything like this in my waking life, so I did some research and learned about casting boards. They are said to be used long before runes were created. Back then they were associated with the elements and such. People would throw crystals on them for divination. Today, the few I found on line are associated with chakras and things like that.



Has anyone used one before? I might try to make my own, I don't know though.
