Actually had a deep sleep, first time in I don’t know how long. I was in Cuba, a spontaneous all-too-short trip, and discovering a tiny all-metal church in Havana that would only fit two people at most, and an incredible ruins of an enormous pre-Colombian city on the mountain(!) above Havana, with elephant trees growing through city walls like in those Khmer cities in Siem Reap (but they were dry and flooded with sunlight here – unlike Cambodia). There were very few tourists wandering about, and the only way to get up there was a rickety van, no usual tourist infrastructure with hawkers, guides and ticket booths, but a sign said to download an AR app that will explain everything. I considered cost of data and did it anyway because I knew that very soon this place will get commercialized and destroyed. I regretted not having read a guidebook, knowing nothing of context of this place, and my rudimentary Spanish.
But then I got woken up and had to get ready for a conference call. I never found out why that city was there or who lived in it.
