Very well said DmnStr8.
Something that may help you understand is the idea of pain. Everyone tenses up, and fights the idea of pain. They panic and make "the pain face" when something hurts. I was always like this too, as its a natural reaction. But I was in a near death motorcycle accident when an oncoming car tried to turn left infront of me. Ill spare you the story, but I have a very high metabolism/tolerance for all drugs. The highest doses the hospital was allowed to give me of oxy and dilauded were barely working. So for the initial two weeks in the hospital and after the first 6 surgeries, I felt everything upon waking up. For hours and hours, I would be in so much pain that my body was super tense, all muscles flexed, my breathing labored.
After some time, you slowly learn how to deal with it. You get to a point where you realize you can just look right at it, and let it in. Instead of tensing up, I started to focus on breathing and imagined I was opening flood gates to let the pain in. Once I let myself feel it all, it was so much easier. I started asking what pain really feels like. It seems crazy, but while being in an immense amount of pain, i started exploring it and wondering what it was. Once I did this it was as if it stopped hurting. The feeling was there, but it suddenly became ok.
I started using a basic checklist. "Am i going to die from this?" The answer was always no. Once this answer is understood, you realize youre safe in that case. That was the whole checklist. Almost like a computer code
If = not going to die
then = ok
Try that exercise next time youre in pain. If you stub your toe or bang your elbow, let it hurt. It wont kill you or cause you any real harm. I now almost always acclimate pain with the color brown. Just think of it and really think of the feeling, and it wont be bad at all.
So this applies to what your experiencing. Just understanding what you did, that DMT is in no way lethal if youre smoking it, and that it will pass. When I spot for people, I say whatever you experience, just confront it and go with it. It will almost always negate a bad time. Even a "bad entity" is there to teach you something if you want it to.
