i'm mad at my cat: you get one of my dreams

My cat keeps waking us up at night, and it is so frustrating. I don't know what her problem is. The only good thing I can find about being woken up is that it allowed me to recall one of my dreams from last night (kind of uncommon for me). In my dream I was researching some family tree stuff. There was one woman who had quite the large number of children, so I asked one of my relatives about her. "Oh sure," that relative said, "that was Right-Hand Mary!" I was informed that this Mary character was someone married into the family who tragically lost her husband and children. I guess she could have been left on her own to marry someone else, but the rest of the family wanted to keep her in "because she could have children with her right (and dominant) hand tied behind her back." Weird, I know. So they had her marry one of the other brothers and she had a bunch of children, which I for some reason (and some way) made frequency distribution tables for and calculated row percents, column percents, and table percents for (can you tell I was working on stats homework last night?). I was a direct descendant, so thank goodness for Right-Hand Mary! I don't know what my dream world is up to.
