Amrita, maybe?
Spice always, always makes me spit. Large amounts of saliva collect from the back of my mouth, and ok am always compelled to expel it with a large force of airbehind it from my lungs. Some kind of purge, yes.
I have no source of empirical evidence to support this conjecture, but I do feel that DMT, and to an even greater extent psilocybin (both tryptamines) promotes biochemical homeostasis.
My experiments with using psilocybin to treat depression and ptsd symptoms have led me to this conclusion,based only upon the way I feel.
I do not feel that dmt provides the same sort of mid/long term stabilization and healing effects but that it does have a certain utility of its own along those lines.
I feel that while my intentional use of other psychedelics have provided me with more personal insights, my encounters with dmt have opened up my understanding of that which is outside of me. I don't think that the dmt experience has one single thing to do with me, it is access to and shows me 'the other'.
That said, there IS some kind of physical thing going on. It is interesting that with the intense change of perceived environment with it, that one's mind seems relatively unchanged. One simply observes the astonishing alter reality that dmt allows us to peek into. However, often,visions include manipulation of the corporeal form by energetic entities. The 'alien surgeon' thing.
I have no clue what all this means.
