When I was young married and bored to death left at home all day while DH worked, I took a numerology class. When I see numbers, dates, birthdays, I automatically add and covert to one number. I don't believe in it but can't stop my mind from doing the math. I was tested and told in HS that I had an eidetic memory. I never pursued it. It's frustrating to remember something and be the only one that does and every one else thinks you dreamed it. I'm not/ wasn't a genius like Sheldon Cooper, just can remember everything.
