A good way to keep track of it all is to go out and buy a Journal and write down your experiences the best you can. I found that when you start writing the experience down you retain more and also it can actually, in my experience, reveal more of the experience that you might have forgot in the moment. Also having a note book or something of that fashion to jot down insights and revelations, whatever you wish to call them, in the moment can also help retain them and then after you come down you can look back on the notes you wrote and rewrite them in detail in your Journal. I found this to be very useful and when in the experience don't write full sentences you might not be capable do to the inebriation, usually this happens on high doses of LSD and Psilocybin around 4-5 grams in my experiences. DMT last a short duration and is hard to comprehend your almost completely immobilized so writing things down is next to impossible but DMT can change your whole thought process in just one journey especially if you breakthrough it will change your life. For beginners the best intention, in my opinion, is to just wanting to know the unknown every trip is different and that's what makes it challenging to go again.
