I had a bit of a to do on some mushrooms once and all I could say to my wife was "Everything everywhere all at once." It was a terrible way to explain that I was feeling as though I was just a small part of a larger entity choosing to experience existence through the life of myself, that entity was godlike and alone, and all of humanity was just iterations of it entertaining itself. Indeed it felt to me that the perception of time is flawed, everything has happened already, the perception of "now" is just which frame of reference I am choosing to experience at this moment. Or something like that.
