Did you ever have an erotic dream about someone you'd previously never thought of as particularly attractive, only to wake up and realize you're now very much sexually attracted to that person? It's only happened to me once, when I was a teenager, but I've never forgotten the experience because it seemed rather bizarre.
My first degree was in Mathematics and over time I have had a few that have involved that. The two that I remember the most are myself both advancing up and down a three dimensional spiral.
