I think if you are searching out a spiritual nature or deep meaning with in the DMT experience it finds you much easier. The people I have dosed that sought out a spiritual meaning in life, when dosing got it, those that were not so spiritual or weren't in search of, did not have that sort of experience.
Intent isn't always just what you apply, you have intent in your life. You just live your intent. That one I think shapes the experience the most. The implied intent just directs it in different directions. Much like in "real" life.
Subconscious intent as opposed to conscious intent.
Although I have also found that with the people who don't necessarily have the subconscious intent we do, they need to work with it more in order to be able to decode the message better. Over time I think most people will have that experience you have. They just have to seek it out within, and it will become available to them. To me it seems to be perceptual blindness.
When the tall European ships first approached the early Native Americans, it was such an ‘impossible’ vision in their reality that their highly filtered perceptions couldn’t register what was happening, and they literally failed to ‘see’ the ships.
This resonates with me immensely when it comes to perceiving the experience. My first several doses, I didn't get the same kind of experience I do now. Even though I had the same subconscious spiritual intent I do now, I think it is more advanced and I understand a little more. Some others I have dosed experienced the same thing. The message was so intense and advanced beyond our understanding that at first the astonishment made it difficult to truly pay attention to what was happening. Over time the message and the method of transferring the message to me became more clear.
Even now, that I have yet to jump back on board with dosing I am finding every few days I get a more clear picture of certain aspects of life and so on as long as I abstain from any substances. I believe once I reach a certain point and am able to go back to dosing my experience will be different and possibly more advanced than I have previously experienced.
