I think they did perciueve the sky differently - it would have looked different let alone had different myths and cultures mapped on it. I love how some cultures see between the stars, the space in between, for images/stories. Symbols and patterns are fascinating - but it's easy to rabbit hole it and make shit up, which is how we arrive at truths anyway, sometimes...

I think once you've done psychedelics your brain gets better at organising or understanding stuff like this. Years later you find yourself completely straight and drug free and looking at the universe through a meditative lens and seeing it like this too. Like your hand could pass through it all.
