When I was a kid in elementary school I suffered with math and multiplication tables. Then one night I had a dream that I learned it all. I scored 100% on my math test the next day, and since then I've been very good with math.
In fourth grade I could add long lists of numbers faster than anyone else.
In college, although I did not like math courses, I got As in everyone I took.
So, dreams can be very powerful.
(And if anyone wants to spell words backward try this: look up and to the left. Visually spell any word so that you can see the letters. Then spell it backwards by simply reading the letters up there in your mind backward.)
