Hey Modern, amigo!
I see you have some standards you look for, like fractals, and open eye visuals.
There are many misconceptions regarding Aya experience that are widespread.
I have only taken my own brews so far in life, sometimes brewing with the influence of friends who know a lot about it, at the most.
Although I had not real open eye visuals (maybe faint tracers at the very most or something very minor), but with open eyes I could certainly drive.
While with closed eyes, I would have full mirations, meet with my Allies, and sometimes interact with them in a very complex manner.
Perhaps a little more light might be desirable sometimes depending on the kind of healing/learning one seeks, or perhaps the righteous nature of the brew, requires, or sort of demands order, alignment, cleanliness, and frugality perhaps also gets rewarded.
Also, during the daytime, is not the best time to take the brew, sure its ok, but the brew, as well as with most allies, its a nocturnal experience by nature.
Thats something that got my attention, because Ayahuasca distinguishes itself from the "regular" psychedelic experiences most have with Acid or Shrooms, and TBH, I don't even find that psychedelic really fits Ayahuasca (but thats just me), because its not just to take it and it does everything for the experiencer.
Ayahuasca demands order, organization, purpose, cleanliness, and the dark of the night, there are a few secrets perhaps to be unlocked.
Sublingual absorption works well for very few things, like Coca leaves for example.
And the MAO enzymes are found through the whole body, and through the blood, hence all tissues are dipped in MAO.
Next time, as to know if you're enough of MAOI, take a picture of yourself in the dark, under a black light. If you have attained MAO inhibition, the most irrigated parts of your face, like your eyes, and lips, tongue, will shine because your blood is shining, full of light.
