The City lights blinked out forever--literally overnight--with a sudden finality that caught even the most nuclear-winter-prepared/Guns N Ammo reading/Campbell's canned soup and distilled-water stocked/backyard-fallout-shelter-owning-survivalists completely off guard. Armageddon had always been there, sleeping just beyond the horizon line of our periphery, but it awoke fully clothed and ready to go to work that day.
It was an ordinary Thursday, just like any other. The MUNI lines were choked as always with angry elderly women clutching plastic shopping bags full of pungent vegetables, poultry, and recyclables as if their lives depended upon the contents of those bags (maybe they did) and the usual gaggle of gibberish-mumbling crazies talking to themselves with cellphones plugged into their brains, some without. 
That day, baristas were 5 minutes, 23 seconds late for work on a city-wide average. Bartenders were making their rent in tips as rowdy soccer fans converged in their local Sunset, Richmond, Mission and SOMA district faux-Irish pubs to watch the latest big championship match between Ireland and...some other country.
By Saturday, less than two days later, the desperate siren-blare of emergency vehicles, the insect hum of DPT tri-bikes carrying cutthroat ninja-sneaky meter maids ready to make their weekly quotas by slipping bogus $55 parking tickets under the windshield-wiper of your best friend's beat-up, barely-working mid-90s Mazda you were borrowing just for the night, and the cloud-cutting rotary-whine of channel 5 news traffic-report helicopters chopping through the sky had been silenced forever.  
As if sensing the absence of gardeners, street sweepers and garbage men, weeds grew out of the cracks of the streets and sidewalks with the newfound urgency of a wildfire. Leaves swirled through glass and concrete skyscraper canyons, settled, and slowly began forming mounds as if attempting to fill the spaces that angry elderly women with plastic shopping bags, cellphone schizophrenics, and drunken soccer fanatics had once occupied.
Speculation about how the End of the World would actually occur had always been a theological reference point for religious zealots hell-bent on giving the Book of Revelations some validity, but had taken on a tone of comical absurdity in the hands of post-Y2K pop culture and disaster movies. A horde of zombies rising from their graves and feeding on the flesh of small bands of living human survivors was one of the more popular, albeit fantastic, apocalyptic theories. Some predicted that robots would enslave us, some thought aliens would invade us, while still others--baring signs reading "THE END DRAWTH NIGH," arms stretched meaninglessly up towards the hollow heavens in the sky above--believed biological or nuclear warfare to be the most likely form of humanity's demise.
But by the following Thursday, speculation had become a moot point; none of it had mattered at all in the end as the power-grid of the City, and then human civilization altogether, had been suddenly switched off for the last time by an alcoholic rent-a-god, leaving the face of the globe devoid of any trace of the spiderweb-night-glow of terrestrial city-lights. 
Only the birds in the sky and the fish in the sea were spared to fill the blank pages of history that were to follow human(kind's) fading footprints.

*

Aeons later...
When those birds learned to read, they would see cryptic symbols inside a crooked heart jaggedly carved into a tree trunk surrounded by a mote of fallen leaves and ragged newspaper pages blowing through the streets like tumbleweeds.
Aeons later...
Those tree-scratched symbols would form the sacred commandments of a secret new religion built upon the ashen, worm-eaten remains of two skeletons holding hands and a ****** trail of broken hearts trailing from their ribcages into the worm-mouths of babes.

Love-Amphetamine to keep feeling,
Speed-Amphetamine to keep moving,
The come-down from last New Years
had me left in a hoop, spinning.

This New Years I feel like a mental hospital
is where I ought to be; the dizziness of freedom.

Bubble-gum MDMA,
Strawberry 2C-B,
Apple 4-AcO-DMT,
Blueberry **-MiPT,
Blackberry Brandy
MethAllyLescaline
and Birthday Cake
-flavour DPT.

How many chemicals will I taste tonight?
Psychem Surprise, no one knows!

DiPropylTryptamine, eucharist
by the Temple of Inner Light;
The godflesh of psychedelia
made manifest, an entheogen.

Immanention beckons with open arms.
I go willingly, to lose myself
in the embrace of The Entheon.

It took many years to track down the compound
but I finally acquired it in the spring of '21.

It caused increases in timbral perception and aural acuity.
I could hear marching drums coming from the city center,
From across the lough I could pick out their faint rhythms.

At times things sound as if they've been shifted a 5th down
or have reverberant/echoic tails on them.

My housemate found it hard to understand me
when I neglected to pronounce my consonants
because I was not paying attention to the higher frequencies.
Despite this the cognitive effects are gentle
and unobtrusive (which is relieving
as tryptamines can produce confusion,
in concert with their enhancement and suppression cycles).

Music is listenable at this dose, and sense of rhythm intact;
Would that be the case at higher doses?

During the offset my ears felt warm,
Waves of spontaneous physical sensation washed over them.
This tingling feeling reoccurred a couple times
over the next day, albeit faintly.

Interesting that there would be an aural psychedelic.
Intriguing that other base tryptamines should be inclined
towards other sensory modalities.

DiPT for sound, MET for vision, MiPT for touch;
What sense DMT, DET, and DPT affect is unclear.
As is, the known psychedelics have a broad range
of effects. The particular specializations of the xxTs
are most curious.

Friends go trippin' through the night
on all sorts: acid, 4-AcO, Mescaline.
We smoke cannabis blended with
oregano, and we freebase DPT.
I wake up on indigo Sunday
and sit across from them
before walking home.
