Thank you for finding and researching this to open a new line on all things futurists. When we have people now claiming 'the science' of futures, then this type of visionary experience tied to physical health is an insight worth reading.
Place it into the time it came from (Metropolis the film and some of the more famous writings on political possibilities) where dystopian considerations were apparent. Also reflect on what could be through the passage of the Anthropocene.
I am sure I am not alone in having interpretations run around as we come to a number of inflection points regarding our environment and what it means for geopolitical organisation and free will - if this was ever a construct?
