Hey, maybe you are watching too many episodes of The Big Bang Theory. You can't watch that show without seeing a blackboard filled with math equations. TBS has the reruns on late every evening so maybe you are seeing it right before you go to bed. But seriously, who really knows why we dream what we dream. I often dream of my parents and several beloved aunts and uncles who, sadly, have all passed. I read a comforting thought one time that that is how they visit us after they are gone. Comforting, yes, true, who knows? But along the line of dreaming of numbers...I have been out of high school for 47 years and I still have a recurring dream of forgetting my locker combination, hearing the bell ring as I fumble with the lock, and being late for class. I can't recall that ever happening in my years at school, but I can remember my combination which makes it really funny, given how simple the combination was: 0-30-20!
