DM Turner- The Esseential psychedelic guide

One can, however direct the tryp by what I will call the "intent of the soul"
or will.
Many users, including myself, have felt possessed by various spirits while
on DMT, as if becoming a medium and channeling alien thoughts. This can
be quite heavy. It has been generally positive for myself and the people I've
smoked DMT with, but I've heard stories from others who have expenenced
the opposite extreme.
On DMT the perception of time slows to nearly a complete stop. During this
stage one may feel that they are not breathing, or that their heart has
stopped. However, this is due to one's state of perception. Many users report
being aware of millions of vibrations and sounds going through the universe
and their bodies, the body often bursting with energies they never knew
existed. One can let these feelings flow through them, or if appropriate,
direct the movements to some type of dance, yogic exercise, or drumming.
These "physically manifesting" energies are gentler on N,N-DMT than on
5-MeO-DMT.
DMT frequently produces changes in the facial expression of the user,
which can appear quite bizarre to an onlooker. It would seem as though the
human face has the potential for a far greater number of expressions than we
normally use, possibly even the ability to carry on sophisticated
communication through facial expression. DMT acts as a catalyst to awaken
this realm of movement by exercising the muscles involved and realigning
the underlying energies. It's also possible for this realignment of energies to
take place in other areas of the body, occasionally instigating a shamanic
dance.
In recent years DMT has become quite notorious in the psychedelic
underground, primarily through the writings of Terence McKenna. And
despite the fact that it is rare and highly sought after, once it becomes
available to those who are seeking it, very few people use it frequently after
a short period of initial use. I've assumed that many people have joy rides
for their first several trips, then have an experience which is extremely
frightening or intense, leaving them intimidated about continuing DMT use.
However, I like a friend's recent explanation for this observation better:
"DMT gets progressively 'weirder' as you keep smoking it."
What I've described about DMT so far can be applied to both varieties.
However, some characteristics of the two are quite different. I had been
using 5-MeO-DMT for a few years before obtaining any N,N-DMT. After I
first tried N,N-DMT I concluded that 5-MeO-DMT feels like sheer force,
whereas N,N-DMT feels like sheer perfection.
