I wonder if this video I just viewed would help you. Your lines could have been some message similiar to the I Ching of China that is very similiar to the Myan, which fore-tells the future. Someone asks a question seeking an answer, The Textor tosses three coins and depending on whether more heads or tails are thrown, a straight line is drawn or a broken line until you have six lines that forms a pattern that is called a Hexogram. The Textor looks up the pattern you have inquired about in his book that holds 64 different hexagram possibilities for an answer.When I saw it, it made me think about your question regarding what you saw. Who knows? It may stir someone else's understanding of these things and lead to a much better answer. g
