I thank you all, (including xss27!) for your kindness, concern, and helpful thoughts--even criticism is welcome, because I posted to hear your thoughts and share my situation with you.
I am at peace with this time of cleansing and re-focus on other things in life-- I just really want to understand the why/how of what's happened, and for deeper reasons than just experiencing DMT again.
Propello, I saw that thread from Glossolalia where he experienced the same thing. It's part of the reason I wonder so strongly what the mechanism of this experience is.
If only to warn/educate/guide others from reaching the same cul-de-sac, which again seems to afflict even short-time users.
I want to stress to you that I don't dismiss out-of-hand the premise that this is some kind of sub- or meta-conscious blocking effect. I'm inclined to believe that it could be some form of mental declaration that I'm not in a life state where I am/can be receptive to that frequency or mode of being.
My soul could be locking me into regular life right now because that's where I need to be. But I don't necessarily want the conversation in the community to just wave off the chemistry and physical realities of this effect either-- because saying "the universe said so" may be right, but that says nothing about "how" it said so!
And while it's easy to just say "if you abuse, you lose" it's not factually correct in 99% of users-- so while such sentiments are emotionally satisfying, they're not accurate for most people and don't explain anything to help others learn from the condition.
I hope this is all coming across as a measured effort to try and shine light on what/how this happens. I want the conversation to be fruitful for future searchers that go through this and stumble upon this thread in their efforts to understand how to navigate through times like this.
