Sounds to me like inhaling a nitous balloon, blowing back into it, inhaling, blowing back, etc.

Five minutes and no replies! Come on people!
So I'll just reply to myself then.
23 numerologically is 5 which is the 5th elemental essence. The quintessential element.
It's not quite air, more aether.
Hence nitrous oxide.
That sound is THE SOUND.
In Aleister Crowley's 777 the element of Spirit corresponds to the sense of hearing. And since those are Crowley's cards pictured in the 10,000 Days booklet, maybe this is relevant.
I've only heard that sound from Viginti Tres one other place. In my head full of nitrous.
It dawned on me about a week ago that this truly noble gas represents the beginning, when the universe was just simple molecules.
Then monkeys (travelling in reverse) discover fire-and don't get love, yet- will/intention.
Humans emerge as a result of experimenting with psychedelics found in the plant/fungal kingdom.
This is why emergency rooms were created(down under).
Then the importance of ritual emerges (Lipan Conjuring). The way it was before New Orleans was settled.
And our mother dies before us. And we can't wish it away with sorcery.
We watch it from afar happening everywhere. Like angels on the sidelines.

put the cracker and the balloon down.

Post 1 left me speechless.

Post 2 put me to sleep.

yowza.

Me thinks Trypto just needs to lay off the drugs...PERIOD

Funny ass thread, can't say nitrous came to mind for me, but this place is always full of interesting ideas.

I would but all this snow and ice has mysteriously covered the ground so apperantly this causes the 3 drag strips in my area to be closed from November to April.

I did drive it around the block and smoke out the neighbors leaving tire tracks all the way down the street ;)
