I'm going to delete this comment soon but, from what I understand about ergine, that's totally possible. You may find on a high threshold dose of 125 flower seeds that you become so enlightened that you start talking to yourself in your head as if you're a separate person from yourself, but then realize that's the way we all think to ourselves. I wish I could type out the understanding in words, but you just begin to know things that should have been so obvious every day. I've noticed that I may have found a possible on-switch in my mind to trigger migraines. It's very subtle. But through the understanding imparted by the medicine, I could totally see myself helping myself identify the on-switch clearly. Just wish I had the 10 hours of privacy needed to try this form of therapy. Just don't crack your teeth if you choose to go that way, because those seeds are hard as rock.

Another way to go about this is through experiential meditation, which (although a very slow process) if you get good at meditation it's basically just like taking psychedelic drugs.
