At high doses, psilocybin mushrooms trigger transcendent, mystical experiences. Many researchers are incorporating these into treatments for PTSD, depression, and other maladies that stem from a crisis of meaning or identity.
There are challenges inherent in using medicines that disrupt the workings of a person’s consciousness. William Richards, who conducts psychedelic therapy at Johns Hopkins, writes in Sacred Knowledge that participants in his studies have felt their sense of self temporarily dissolve after a dose of psilocybin.

Most commonly, the term “death” is employed as the ego (everyday self) feels that it quite literally is dying.
Though one may have read that others have reported subsequent immersion in the eternal and experiences of being reborn and returning to everyday existence afterward, in the moment imminence of death may feel acutely – and for some terrifyingly – real.
Because this sensation is so frightening, most researchers recommend a trip-sitter – in Richards’s words, “having someone present who one honestly can choose to trust without reservation. The attitude ‘I can manage on my own and don’t really need anyone else’ clearly can be very counterproductive in some high-dose sessions when the ‘I’ needs to totally relinquish control.”
At times, an arrogant attitude of self-reliance is unhelpful. It is also, unsurprisingly, the attitude with which I approached nearly all aspects of my life. I’m an athlete, an academic, usually in full command of my own mind and body. I mostly work alone (although I’m very grateful that my spouse helps me run this website).
Why wouldn’t I do my own psychotherapy?

I tried psilocybin mushrooms during graduate school. Shortly after we met, the person who is now my spouse asked if we could visit her sibling in Portland for her birthday. We left Stanford at 7 p.m. on a Friday, then drove north through the night. We arrived at about dawn on Saturday morning, collapsed, and slept until noon.
We were visiting a punk house, it seemed, where the bulk of the rent was paid by one person’s trust fund, with others occasionally chipping in money from various odd jobs (there was a nearby sporting event during the second day of our visit, and one of the housemates put on an official-looking reflective vest and charged people to illegally park in an abandoned lot down the street). A dozen misshapen mattresses were strewn about the skunky-smelling attic; I picked the second-least stained to sleep on.
On Saturday night, for the birthday celebration, our hosts threw a party. Several bands played – it was the sort of event where the scrawny white weed dealer’s terrible hip-hop group (bass, drums, and the dealer on the mic) was allowed to play a set. The others were mostly metal bands.
One of the housemates (the faux-parking attendant, as it happens) brewed a large mason jar of psilocybin tea. As he was gamboling about the house, we crossed paths and he proffered the nearly empty jar: “Hey, man, you want these dregs?”
I shrugged and drank it.
“Whoa,” he said.
“What?”
“Just, that was a lot of dregs.”
Which, honestly, was not the best moment to be warned. I’d already drank it. I obviously couldn’t do anything about it then.
Richards and other medical professionals involved in psychedelics research would find it unsurprising that the tenor of the evening turned intensely spiritual for me. Ken Kesey and other psychonauts would find it unsurprising that the goings on seemed exceedingly trippy, as well. I sat on a couch in front of the bands’ performance area and watched as a singer seemed to smear her face across the microphone; soon I saw her with three mouths, the two in her neck relegated to singing harmony.
I felt intense paranoia; as I waited in line for a bathroom, people nearby seemed to be snickering at me. Of course, snickers often follow in my wake at parties – my behavior can be outlandish – and I might’ve been making goofy facial expressions.
I understood only snippets of conversation. A squinty-eyed Thor-looking blonde man named Hyacinth was saying, “I always wanted to get with a Gemini, and then, bam, last winter, I met this older lady with these, like, enormous eyes, and I was like, whoa, and wouldn’t you know it, bam, she’s a Gemini!”
(I later learned that he worked as an, ahem, “intimate massage therapist,” or “hired companion,” that sort of thing. He also cornered me and spent thirty minutes explaining his take on quantum mechanics. His version involved a lot of positive energy radiating from crystals. The abundance of positive energy in his own life is part of what brought him together with that Gemini, it seems. The waning disorientation from psilocybin left me totally unable to extricate myself from the conversation.)
And, as per Richards’s expectations, I felt myself losing a fundamental component of my identity. I temporarily forgot how to speak. Then felt as though I was losing all ability to translate my thoughts into external action.
Perhaps I should’ve noticed that I was still passively influencing my surroundings – nobody else could stand where I was standing, and Hyacinth wouldn’t have stood there simply lecturing the air – but the flickering of my short term memory caused these examples to slip away from me. I felt like a ghost, and the sensation terrified me.
But I was lucky. Even at parties (to be perfectly honest, especially at loud parties), I carry a pencil and paper. That way, I can draw horrible cartoons. Sometimes I try to use these to communicate.
It should come as no surprise that I make few friends at parties.
I found a secluded corner of the party and began to write. And then, minutes later, when I felt another wave of loss of self pass over me, I was able look at the sheet of paper in my hand and see. I wrote that. I did change the world. I am changing it.
I was able to regain a sense of object permanence, despite the ego-erasing effects of psilocybin. If I were a ghost, my marks would wisp from the page like so much abluvion. But here they are.
Because I can still communicate with the outside world, I still am.
In all, the experience was probably good for me. Someday I could write about why. But for now, I’d simply like to stress that, in that moment, writing saved me. Writing kept me anchored and tamped down the terror sufficiently that I could accept whatever was happening inside my brain. (Indeed, one of the things I wrote that night was, “Without this paper, I’d wander the streets, wake tomorrow in a gutter with a rat gnawing on my eyeball.”)
And I’ve seen the way that writing has saved other people, too. When people fear that they’re turning into ghosts – cut off from the outside world, unable to reach their friends and families – even severely dyslexic men will start sending letters.
Being held in jail can dissolve a person’s sense of self just as surely as psilocybin mushrooms.
Each week, I bring in another dozen pencils. I occasionally wondered what was happening to the pencils, whether they accumulated like Lincoln Logs in the block. But I kept bringing more because we need a way to write during our class. And I’d let the guys keep them. So much has been taken from these men that I couldn’t bear to ask for the pencils back.
Eventually, somebody told me. “Oh, yeah, my bunkie, he writes a lot at night, he always sharpens like a dozen pencils before lockdown.”
The men in jail aren’t allowed to have pens. They can’t have mechanical pencils. And they don’t have sharpeners in their cells.
At night … or if there’s a disciplinary infraction … or if the jail is understaffed … the men are locked into their little cells. Unless they sharpen pencils beforehand, they cannot write. Each broken tip brings an inmate that much closer to enforced silence, unable to communicate with the outside world.
Recently, people have been forming a big line at the pencil sharpener whenever I teach class. I slowly pass out the poems that we’ll read that week, then pass out pencils, then pass out paper, then sit and wait. The waiting takes a while. Guys come with twenty or thirty pencils bristling from the shirt pocket of their orange scrubs, then stand and sharpen all of them. A dozen men, sharpening perhaps twenty pencils each.
At the table, they mention trades they’ve made. Losses, due to theft: “At the beginning of the week I had fifteen pencils; now I’m down to three.” They exhort me to bring more. I say I’ll do my best.
“There’s only one pencil sharpener in the block, and it’s been broken for three months. It’s like that one, a wall mount. The gears are all screwed up. The handle was broken off, but you could sort of still use it then. But now, anybody who doesn’t get to come to your class can’t sharpen any.”
“I’m sharpening some for my bunkie,” yells the guy currently cranking the handle. A few of the others nod; they’ll also sharpen some for charity.

Twenty … thirty … maybe forty sharpened graphite tips. While those last, the guys will be able to write. Time will pass, but they’ll be able to prove to themselves, and to the outside world, that they really do exist.
With luck, those sharpened pencils will last all week.
