I'm always browsing worldwide surface and overlay net in the searching of rare magic stuff, days ago i've found these squares on some russian magic website, site looks pretty cool. Okay i've tried to translate description for one of these squares.
"SQUARE OF ANU BEL for a lucid dream. SQUARE is should be drawn with your own blood, perfumed with incense, cast spell upon it : "EYHU ENIEL ANU.GEPAR Assou Maradi. ERESHTI KI NERGA FAA. MINNAS." READ seven times. Before going to bed SQUARE must be placed under the pillow. Before going to sleep pronounce spell seven more times ABOVE THE aquare, and then name what you want to see or know. THE NEXT DAY SQUARE must be burned, the ashes must be scattered. One time per week only. Try not to abuse these squares
