Whoa, that was an intense report for sure.
Still no sign anymore of the OP?

Granted, it's been 11 years but this device/ship
really intrigues me as the dissonaut that I am.
While I currently, off stronger NMDA antagonists, don't have too much access to that world, it's memories and features (there indeed is a huge state dependent memory with dissos and all of them have plateaus, a bit different than these of DXM but a good part of White's FAQ is more or less applicable to dissos in general.), this will become a rather short posting. But I fully understand the feelings of the OP from my own experiences with DXM, MXE, K and 2F-/DCK. While N2O apparently isn't just a NMDA antagonist, and I only tried it once - after reading this here, I'll have been much too focused on breathing enough oxygen that I didn't reach effective levels of the gas very probably. But it all sounds so much similar to specially DCK. The understanding of it all, the love, the incredible meaning and devotion, the loneliness with all (even when I can't truly imagine how it must have felt w/o the internet, not knowing about just a single other gasonaut), the desire to invite others into the dissoverse, the acquired control and influencing / potentiating / leading the experience with music, light etc.. Oh, and too the addiction. People seeing and judging that.. spiritual hobby research.. as obsession, addiction and/or self harm.
But thought the mechanism of N2O was known and would be primarily NMDA antagonism? GABA activity does water down the experience. Opioid can be synergetic.
Was curious about the other way round of combining DCK with a psychedelic and particularly DMT, or Salvia but was too afraid of potential anxiety based on bad shroom trips many years ago. Until recently when I read here that not only does possibly the combination lower the risk of anxiety but even scientific papers suggest that the DMT (or psilocybin) actually
protects against possible toxicity of the disso..
DCK alone was exciting enough and I can only speculate based on trip reports about how it must be and feel combined with psychedelics but I guess amazing.
I am unsure about the character of this 'understanding the universe' thingy. It is more a feeling than knowledge, but too a mix of both. But if you really could bring something like evidence over in our everyday reality. I have briefly experienced emotional telepathy, possibly but not really sure about, verbal too. Many things tend to feel possible but I know the scientists say it's all just on your head. I don't necessarily identify 1:1 with this, some reports say you could meet entities or beings in the dissoverse and many about DMT but up to now I always was the only ecistence there. With the relative absence of many negative emotions and them being replace with love, peace and hypomania, it doesn't feel lonely the way it does while sober and is amazing enough but being able to enter this space together with somebody else or even to meet others there would be fantastic (and when hearing / reading about e.g. schamans I wonder how far they actually manage to go in these spaces. Things sound very similar enough to well possibly be different ways and approaches leading to the same destinations.)
And it would be so great if there was no need for hiding. Umm, somehow feels like I don't find the right words for all but don't want to discard either..
