In my keyboard class several years ago my teacher got a little off subject, and we had a class discussion about visualization. Apparently some people see things in color. I'm not talking about The Wizard of Oz. I'm talking about days of the week, numbers, months being associated with a color. I realized that I don't think in color. I think in shapes. All of my days of the week are rectangular, but they are all different sizes. Monday is tall and wide. Tuesday is tall and very skinny. Wednesday is short and wide. Thursday is medium wide and tall. Friday is almost a square it's so short, and Saturday is so large the edges are nonexistent. Sunday is still a rectangle.. but it curves around to Monday.
Numbers aren't quite as exciting. 1-10 is a vertical line w/one at the bottom and 10 at the top. 11-20 veer off to the left in an upward curve, then it is diagonal switchbacks moving to the left every 10 numbers to 100. I could go on, but I fear confusing people.
I am sure there is a method to my madness. If you figure it out, please let me know!
