DXM taught me that life is an inverted paradox full of transparent layers upon layers like an onion. Sometimes you don't know what layer you are in and sometimes you stay in the same headspace for years but it is really a day, with dxm you can travel to any point but when the trip is done you always end up one layer deeper in experience, like each trip is a ring on a growing tree, everything is infinite facets and layers. Some can be the best, some can not make sense, some can't even be explained in language but if you are feeling down, take a trip and transport up, left, right, black white, in out, red blue, dead alive, A to Z, X to Y, upside down to outside in, infinite realities man
Also meth, sleep deprivation, amphetamines, methylphenidate, opiates and deleriants like doxylamine and benadryl make me feel like I'm in an alternate universe temporarily while life goes on with my alternate self in our universe, could also explain blackouts, and astral projection, going to a different perceptual reality but you can't remember because it never didn't not happened
