Cain and who?

This is going to sound really strange but I had a dream last night that I became the proud mother of a pair of newborn twins. A boy and a girl. And I don't know if it's because I taught Theology of the Body last night at church or what, but it entered my head that I was Eve and that my twins were supposed to be named Cain and Abel. I was distressed because of course, I did not have two sons. So, I improvised and named them Cain and Mabel.

How does my head come up with this weird stuff while I'm sleeping?
