When you have been working on your dissertation for a a long time (subject to your own interpretation of a long time) and you start to forget random but important information.
Today , I forgot what year it was. I swore it was 2015 and an hour into working and dating everything 2015, I realized it was actually 2016. That is when I realized that I had dissertation brain. #dissertationbrain

This could be used to describe the brain of any writer, but i believe it to be a periodical and temporary experience. It is when someone is in the headspace of being poetic or saying and thinking beautiful, deeply emotional crap. It’s truly haunting. Non-writers don’t understand this, but it’s a flurry of emotions. It’s also motivation to want to write, which normally doesn’t result in writing anyways.
“I just want to be loved like a fairytale right now, i want someone to gaze into my eyes... oh shit... i have Writers Brain right now!”
