My understanding is that if you have a lot of deamons inside then your ayahuasca experience is going to be more challenging, and the inside might not look so pretty.
But, hey, I am no expert, and maybe I would even be a bit more chicken-shit to deal with myself... I have also heard that sometimes ayahuasca can help to slay some of the deamons too... I suppose, even if those deamons happen to be bears... might be good, no?
You may need to return ur selfie to peru... confront the deamons and perhaps even become "good friends" with the mountaineous creatures in the midst.... let the boy come out in you, perhaps? what happens in peru... blah blah blah..

Psychedelics in general just amplify what is already going on inside you.
Hence if you're having a hard time with life, then that will be amplified to extreme and potentially life-like levels with all your insecurities and problems taking "real" shapes depending on the dosage that you've ingested.
As horrible as the experience might be, it can actually, in select cases, be good for the person as it forces them to confront their problems.
So far I didn't have anything anywhere near as extreme as the horror stories that I've read on the internet though, and I can't imagine myself ever having any of those experiences either.
But I've also made it a point to remember what I did prior to the experience, which takes off the edge. I'm also quite curious as to what is going to happen during the moment of death, since it's quite obviously just a fairly tale that humans tell themselves for the lulz. And then, with a high enough dosage you lose control anyways and at that point it doesn't really matter what happens since you just fully dissolve in what is happening (if anything at all).
However, I could imagine that the tea that shamans brew in their filthy pots in the jungles with all the resulting vomitting and diarrhea could have a very different impact on the person though. Which is also why I'm not particularly interested, although I've had an experience with throwing up on the come up before, which while fucking hilarious, wasn't something I'd need to repeat in that form.
All the same is true for cannabis as well by the way, which is why some people with certain characters get overly paranoid on it. The trick is to distract yourself and to just fake it until you make it. At some point any onset of paranoia just becomes a predictable meme to laugh at (disclaimer: do not try at home I'm not a doctor etc).
P.S. Is there a correlation between recreational experimentation with substances and the openness to Bitcorns, or are those substances just more wide spread these days due to pop media references and documentaries?
