REPORTI did a lot of researching about how to make DMT and after gathering all the ingredients to make it, using the lazy man's tek (with the most pure ingredients I could find and choosing the long walk), I made (after one batch just for tests, trials and errors) 20g of, what I think based on reports of this forum, good quality DMT.
From that 20grams I took >100mg to make a finer powder, I was planning to snort all that (Remembering that it was my first time to DMT or any entheogen!)
After watching "Cosmos" I decided to go to my bedroom and snort all of the 100mg powdered DMT, I'm full of questions but one in particular (not related to "Cosmos" ) I wanted to know with certain urgency: How can we evolve socially.
So I went to bed and, due to pain, could snort only half line of the powder.
10 seconds later I thought: "Where's the trip? Nothing happened...". After lying my head in the pillow and closing my eyes, my arms and legs almost immediatly (2-3 seconds) shut-off, I started to sweat a lot and could barely talk, so I was chanting a mantra in my head: (in portuguese)
"How can we evolve socially, please help us"
"How can we evolve socially, please help us"
"How can we evolve socially, please help us"
...
I felt, in the first minutes, that I was being taken in a hurry to a good / safe place, and then, out of nowhere I saw (what looks like) Ganesha (I'm an agnostic person) and she clearly blocked me to continue the travel, after that I was slowly coming back, feeling loved, cared in a cozy atmosphere. I felt very frustrated to be blocked, but then, slowly, I accepted that decision.
What I'd learned:
-Snort DMT powder is painfull, but the pain lasts few seconds (probably depends on how someone can deal with pain).
-Clearly being in an hurry and, specially, an overdosage does not mean the experience will be fruitful.
-Bad trips could happen with one who could not manage is feelings, sometimes I have sleep paralysis and, I think, that that helped me to train on how to manage my feelings when "dreaming".
-Cats feel, for sure, when some one is tripping.
-LOVE seems to be an answer (how/when to give/get are other specific questions).
Paraphrasing Liam Neeson in "Taken" (2008 )

"- I don't know who you are
but I don't have to find you to LOVE you all"
LOVE, no matter what.
