Exactly. This is much deeper than everything else I know and tested. 20 years and it still feels like changing me every day, just a little. And there are more layers than both of us have seen. My journey was longer, ~7 hours and I sometimes had to interrupt it with thoughts to not get sucked into worlds that I was not ready for. And now I want to do it again but my next travel there will be in a far future.
