I haven't broke through on DMT, I've had some sub breakthrough experiences though. However, I've had some fairly high dose mushroom experiences, and I often start hearing the same combinations of syllables and they sound really gnarly and either start pumping me up or scaring the living crap out of me, hahaha.
O'Niemity (rhyming with enmity) is a main one/seems to be a root of some of the "sentences" I hear.... sometimes I wonder if I should keep that secret though, might edit it out, blah.
I find it really interesting and oddly enough the "accent" seems to be american english, even though the syllables are totally weird and foregn (this would probably support a skeptic's theory that it's a brain glitch but I swear I cAn fEeL tHeM, mAaAaAn
)
I have to say, I don't find the things you posted very familiar but I have no reference of knowing if you were 100x as high as me and what you're experiencing is far more vivid than me... and DMT vs. mushrooms, etc.
