I am having lots of very vivid dreams of extremely mundane activities that I can't do (or at least feel extremely dubious about doing) in the waking world. Sitting in crowded cafes. Attending a boring work-related conference talk. Riding trains and buses with friends. Queuing for the toilets. (Ok that last I really really needed the loo when I woke up from it.)

The key commonality is that in the dream I'm not worried at all. I don't think about masks or distancing. It's completely fine to be in close quarters with a bunch of people many of whom I don't know. And then I wake up and remember it probably isn't.
