Or there is no such template by default, but DMT causes it to be created in a similar way across people taking it, and the differences in what people experience are filled in according to their personality/life/... Sorry, too busy too look up the exact terminology and hypothesis now, but IIRC there's these 2 major theories on how the mind/drugs work: one camp (a bit like your statement) says things are built-in and certain feelings/states/thoughts/.. exist by default but in a 'normal' sober state the neural pathways to them are not active, and drugs just open the correct gates to be able to access them; the other camp (more like what I wrote) says drugs alter enough things in the brain to create those feelings/... from scratch i.e. not opening a gate, more like creating a gate then opening it and keeping on creating what lies beyond. I can recommend the thought experiment of trying to figure it out which one it is, especially when on drugs, it's rather interesting :) Personally I settled for believing it's a mixture of the 2, mainly because I find it hard to believe the circuitry for some of the things I experienced is readily available whereas at the same time once you have a certain experience it can have a lasting effect and the neural connections remain somehow, making it much easier to have a similar experience next time.
