Code Trawling in my Dreams

A very strange dream occurred to me last night, causing me to wake up and think "I will not be that person".
Whether it was the whiskey, the painkillers I am taking for my shoulder, or the serious misgivings I have about going to my MA course on a Tuesday, I dont know, but it gave me cause to ponder.
In my dream, there was a very scary bint of a woman, long straight flint grey hair, spectacles on a chain, giving a lecture to a room of terrified and bemused students. She was talking about "code-trawling" and how that applied to an extended family from some remote part of the US and how they developed their own language and syntax or some other way of communicating with each other. I cant remember the exact details but this woman had clearly done a shitload of research and travelling and lived in a very unique world of her own, a world that others felt pretty much excluded from and a world that no-one else cared about nor really wanted to step foot in. This woman was really dogmatic and obsessed, and that came over as a terrifying dominance - almost aggressive - and that is what made me think "I dont want to be this person". I'd rather be a nice sweet little old lady painting landscapes in a cottage in the country than this scary bint of a woman.
