I really want to try DMT but terrified to do that without professional help nearby e.g. on an Ayahuasca retreat. I have experienced both LSD and shrooms but have heard DMT is on another level.

I concur. LSD is heaven, shrooms are ok, and salvia is just weird. However, both DMT and ayahuasca feel just too extreme or scary to me. Could also be that I just grew older before this stuff became popular.

I'm brazilian, and lived a big part of my life in a city where there were two religious groups who did ayahuasca. In my 20's, I had quite a lot of friends who tried it, with some doing it quite frequently and a few even joining the groups as full members. The experience I had with knowing them before and after ayahuasca not too different than with other drugs/hallucinogens: my friends related life-changing events, co…

>“Now you see here,” I said. “Everyone in this conversation is in favor of universal love and transcendent joy. But I’ve seen the way this works. Some college student gets his hands on some DMT, visits here, you guys tell him about universal love and transcendent joy, he wakes up, says that his life has been changed, suddenly he truly understands what really matters. But it never lasts. The next day he’s got to get up and go to work and so on, and the universal love lasts about five minutes until his boss starts yelling at him for writing his report in the wrong font, and before you know it twenty years later he’s some slimy lawyer who’s joking at a slimy lawyer party about the one time when he was in college and took some DMT and spent a whole week raving about transcendent joy, and all the other slimy lawyers laugh, and he laughs with them, and so much for whatever spiritual awakening you and your colleagues in LSD and peyote are trying to kindle in humanity. And if I accept your message of universal love and transcendent joy right now, that’s exactly what’s going to happen to me, and meanwhile human civilization is going to keep being stuck in greed and ignorance and misery. So how about you shut up about universal love and you factor my number for me so we can start figuring out a battle plan for giving humanity a real spiritual revolution?”

One of the worst side effects of cannabis :[ I miss dreaming and REM sleep. feelsbadman

I starting dreaming again after years since I stopped watching porn. Took me a bout a week of abstinence. There seems to be some merit to nofap. Might be placebo, but so far I'm not complaining.

Interestingly enough, they learned that increased neural signal diversity resulted, and when someone was "peaking" on DMT the brain was also lit up significantly. This is akin to the research found in dreams and R.E.M. but it's still rather inconclusive as to whether or not inducing such activity in the mind results in the associated conscious experience. Many materialists believe this to be the case, but this does n…

It seems difficult to say the least to maintain a non materialist point of view in the face of all the evidence that chemicals alter mental state.

I thought the same thing until I had my first experience. Now it's hard to maintain a materialist point of view...

Interesting! When you say executive functions, could ADHD be linked in a way to this? When I "zone out" it feels like REM dreaming while awake.

Oh, um, that’s interesting. I have found I can make myself dream while awake in a way... I use relaxation techniques on myself all day and it’s actually a bit frightening what you can make your own brain do... What happened to me is I became more openminded, more fluent in my writing, more daring in my choices, and actually also more socially aware... I can only compare it to eating the forbidden fruit of the garden…

Hey friend. I just wanted to say that I grew up with a parent that was addicted to ADHD meds and he used to say eerily similar sounding things when he was in the thick of it.

If your honestly doing better I’m happy for you.

But if you’re doing _anything_ without the supervision of a medical professional with experience with amphetamines and ADHD, please please please, for the good of yourself and those around you seek out one.

The Substance Abuse and Mental Health Services Administration was amazingly helpful and kind to my dad. Their number is 1-800-662-HELP (4357)

I’m just an internet stranger, but your words are eerily similar, and I couldn’t in good conscience not say anything. <3

Ok, we've changed the title above from "Ayahuasca alters brain waves to produce waking dream-like state, study finds" to that of the article.

> It has changed me for the better. Is that the old you saying that, or the new you?

That's very meta. And an excellent philosophical question!

Assuming you can remember the old you, I think in most cases it's fair to say that it's the new you that has enough knowledge of the old you.

It's just like normal learning really, if you learn something, you become a new you that has knowledge of the old you and the new you might then say "what I learned right now was better."

I know, I'm not the best at philosophy.

If you're asking whether DMT facilitates some kind of metaphysical communication, the answer is no. However, it's possible that a common environment or shared experience before or during the trip could seed similar or related experiences.

The reason I ask is that Graham Hancock in an interview on Joe Rogan was saying that specifically Ayahuasca would allow people to see the same thing, exact same events, whereas DMT would not. Perhaps I misunderstood what he meant. He seemed to imply there was something intrinsically different about the way that was prepared and used traditionally and how it affected people. He seemed to imply it connected people.

Ayahuasca is typically consumed as part of a larger ritual ceremony that steers the participants towards a particular experience (depending on the Shaman you may be told to expect to encounter a certain entity named "Mescalito" for example.)

Has anyone ever tripped on Ayahuasca/DMT and afterwards embraced the thought that everything they experienced was simply a hallucination or dream that they cannot actually integrate back into their regular, sober, waking life?

I've taken Ayahuasca more than once and every ceremony was something that I could integrate into my life in one way or another. As with all similar substances, the setting and preparation make a huge difference, it should never be done recreationally in the spur of the moment but rather with guides who have experience. NEVER TO BE DONE WHILE TAKING CERTAIN MEDS LIKE ANTIDEPRESSANTS, OPIOIDS, ETC I have never done straight DMT, but from what I have heard I consider it to be a very different experience. Ayahuasca is a very unique experience to each individual although there are indeed stories that are shared such as seeing "machine elves", confronting snakes, feeling unbound from time, meeting a higher entity, etc.

You still dream while on cannabis, I just don’t think you are able to record any of it to main memory. Actually from what I understand it we all dream a lot (with or without cannabis) we just can’t remember most of it.

According to Matthew Walker (Berkeley researcher on sleep), it does affect sleep. See this small clip, starting at 2:14. https://m.youtube.com/watch?v=lRp5AC9W_F8

The previous comment is still correct: even without weed we dream a lot and don’t record most of it.

Alcohol in our system at bed time impacts sleep as well. We’re consciously at rest (or blacked out from over consumption if that is ones thing) but our body is busy metabolizing.

Poor signal, YouTube isn’t loading. Not sure if the clip is similar, but as I understand it recording a dream and restless sleep from metabolizing substances are separate processes.
