While on LSD, I can easily breakdown the points of an N20 experience that makes it so wonderful. Here's a description of the effects of N20.
The "truth". The white light, the peak, the high frequency squeal that rushes past, pulling a smile across your face with the visuals of huge, toothy smiles duplicating themselves around your vision. That feeling that the beat of the music is speeding up to a crescendo, while in fact it’s an auditory hallucination.
Sound rushes to an insanely high frequency at super speed and it feels as if time has slowed down to a nano-second. It sounds as if the blaring music in the background’s beat is speeding up to an enormous climax, while in actual fact it’s at the same tempo as before you hit the laughing gas.
You try beat-matching with the DJ…Trying to time yourself so perfectly to the climaxing break that you can pump a fist in the air not even a fraction of a nanosecond away from the beat exploding into a huge crescendo (Your peak breaks as the DJ drops the beat.)
It’s as if you’re moving in real-time, but the world around you is going super-super-slow. You can look around, hear and see what each person is involved in: one group is doing this, these two are talking about that, this group is mingling with that group, these people are trying to do the same thing as you. Matching your flamboyant movement with the break of the beat’s climaxing crescendo. You want to walk up to them and ask them if they’re successful in their efforts, and then you realise these things aren’t actually going around you, it’s just that second of the NO2 peak being stretched into minutes.
The sound hallucinations start rushing back, like an elastic band that’s been stretched and then let loose…It feels like time itself is suddenly speeding up to its normal point and everything slowly moves from freeze-frame, back into real-time and it seems as if single second has been frozen for what seems like eternities.
You feel as if you just did something spectacular, absolutely awe-inspiring in front of everyone but at the expense of snapping your mind into permanent psychosis. You hear the faint “Do it again! Do it again!” and wonder what exactly it was that you did.
During the direct aftermath you could be terrified into thinking that a lot has gone on (or is even still taking place) around you, hours even years of events are going on around you and you can’t escape that frozen second. This sensation will eventually fade away and you’ll become fully sane. But not before thinking how simple (or incredibly insane) that combination of effects is and how you’ve worked it all out…
The key to pleasure.
There is a feeling of cleansing, intellectual release. A feeling of euphoria travelling along your brain’s reward pathway
It is the reward of solution that brings us such pleasure, and while thinking this, you let out a little laugh at how simple it all is.
