I understand your theory. However, the negativity in this experience was strictly physical and prior to ayahuasca I never had a bad experience on psychedelics in my life. I was always fearless and trying to go as deep as possible (hence trying Ayahuasca). However, something was extremely different about this ayahuasca experience. At about the 90 minute mark was when it was no longer fun and I noticed my body had gone very cold, my limbs felt dead, and I felt like I weighed 2000 poinds. Everything was buzzing like I had neuropathy and I saw the white tunnel of death (which kind of looks like a spinning particle accelerator). I needed to gasp for breath and could barely sit up. I was starving for oxygen, couldnt breathe right, and seeing stars. There were no more visuals - just the stars and static of someone who was being choked and passing out. I was certain I was dying. After realizing I wasn't getting to a hospital any time soon, I said my goodbyes to everyone and surrendered my life. I proceeded to sort of black out for the next 6 hours.
Again I dont remember any visuals or anything meaningful - just sort of on and off blacking out and praying for my life. Oh and vomiting no less than 100 times. At some point the ceremony was over and I was supposed to leave, but I wasnt ready and it took me another few hours in a sort of catatonic stupor to gather my composure to be able to walk out. I was asked about my visuals and if I saw any spirit animals, etc. and I said all I saw were some geometric patterns, which confused them. They asked over and over and I just pointed to their robes. They handed me a survey to fill out which I thought was hilarious because I couldnt read still. Looking back it doesn't seem like a psychedelic experience at all but rather just being knocked the fuck out and brain damaged. Maybe it was serotonin syndrome.
I also had trouble the first time I tried "weed" where a few minutes after taking several puffs because I wasn't getting high, I started seeing stars and then totally lost consciousness, and according to a friend I convulsed and threw fists at him. 10 minutes later I woke up from some deep dream not knowing what planet I was on, took minutes to regain my bearings, and felt like shit for the next 2 weeks. But that was nothing like the ayahuasca trip. I'm just wondering if my brain isn't able to metabolize certain drugs. Inbetween the weed and the ayahuasca, I did have a stellar career with some other classic drugs though
That sounds pretty terrifying. Another reason for me to stay away from Peru, as interesting as the environment sounds. Luckily safer substances and ROAs can go just as deep as ayahuasca minus the negative side effects.
Ayahuasca is pretty much a combination of two substances, DMT and a MAO inhibitor, and then some random stuff depending on what shaman you're with. The MAO-I basically allows the DMT to become active when ingested (as opposed to smoked or injected), but it also creates the risk of serotonin syndrome, the symptoms of which sound like what you're describing.
If that's what happened then the weed experience seems confusing though, since it can't trigger SS. I've had some "negative" experiences with weed to say the least, but I never really passed out. I got close once when my entire field of vision got filled up with tiny turquoise colored donuts and my legs felt like gummy snakes. Somehow managed to get home and just lay down. Other times I've paid too much attention to my breathing and/or heart rate and freaked myself out into believing I was dying, but never anything quite as extreme as what you've described. Absolutely zero negative experiences with harder drugs beyond the usual "did I take too much" or "was this a mistake" kind of thoughts that accompany the come-up of every great trip, at least for now (fingers crossed that won't change).
Have you talked to your doctor about the SS possibility regarding your current condition? Or was that unrelated?
