Fun Fact: I sleep with the TV on all night.
It varies between space documentaries and geology documentaries. It also leads to absolutely no dreams that I can remember. I am convinced my sub conscious is watching TV all night and has no time to make up dreams. Despite me priming my brain with docs all night to watch, I really don't know as much as I should about geology. None the less a boat ride around the north Newfoundland Coast in the summer left me with some beautiful rock formation photos.
