An MIT study said our current society will collapse by 2040, so the calendar you saw fits the time frame. https://www.vice.com/en/article/z3x...it-prediction-that-society-will-collapse-soon
I would often dream of driving down the road on my butt; in other words, I was right on the pavement sitting upright with my legs stretched forward as though I were driving a go-kart, but there was no vehicle...just me, somehow toodling along, holding my hands on a steering wheel that was not there. Now that I think of it, the experience was not unlike driving my '59 Bugeye Sprite, where I sat just about that low. I cannot recall if this was a pleasant dream or a high-anxiety dream. It's been a while since I've had it.
