Wow, man. My heart goes out to you. That you came out of it with those insights shows you're on your way to enlightenment. I don't think I'm enlightened, but your report really sent some familiar chills and thrills through me of my DMT experience a year ago. All my thoughts were "breaking", just like yours, my emotions were fractalizing or something. My body slowly exploded away into blackness, where gray fractal entities danced around at me, changing their movements with my rapidly changing emotions.
There's this Doctor, Ernesto Spinelli, who says that society is obsessed with
meaning, and especially dualities, like good and bad. And by giving things names we see them for what they mean to us, their use to us, and miss what they are in of themselves. We miss the ungraspable, beautiful
meaninglessness of everything we generalize in this way. I know also that our minds do this to just about everything in order to not waste brain power in seeing every little pattern at once. Dr. Spinelli concludes that when we come to terms with what no one can explain for us, death -- the ultimate embodiment of meaninglessness -- all the meanings that were based on illusion are swept away, and, somewhat paradoxically, we can finally begin to live truly meaningful lives.
You say you saw that the world just is. Maybe you experienced something so new, that none of your mind was used to seeing even the tiniest fragments that made up this totally new crazy experience. So, in a way, it was the death of everything you knew, of all the meanings.
You had quite a ride, friend. Give yourself plenty of time to enjoy everything that is now new. The world welcomes you back, and beckons you to welcome yourself to all its wonderfullness; there's so much to see and do and love to feel and give!
