I Wrote a Memoir for the Version of Me Who Said Yes: The Strange New Genre Nobody Saw Coming

Somewhere out there — in some branch of the quantum foam, in some adjacent reality your physics professor might half-jokingly acknowledge — there's a version of you who took the job, stayed in the relationship, moved to Portland, or finally started the band. That version of you has a whole life. And increasingly, people are sitting down to write it.

Welcome to the multiverse memoir: a quietly exploding genre where real people craft fictional autobiographies for alternate versions of themselves. It's showing up in TikTok threads, Substack newsletters, self-published paperbacks, and MFA thesis projects. And it raises a genuinely fascinating question — are we using imaginative storytelling to understand ourselves better, or are we slowly outsourcing our sense of identity to a reality that doesn't exist?

From "What If" to Chapter One

The format varies wildly. Some creators write in first person, inhabiting an alternate self as though journaling from inside a different timeline. Others frame it more novelistically, referring to their alternate version in the third person like a character study. A few lean into the multiverse aesthetic explicitly — timestamping entries with fictional dates, inventing parallel-world slang, or building out entire alternate histories for their fictional selves' cities and families.

What they share is the emotional core: a real person using speculative autobiography to process genuine feelings about roads not taken.

Creators on TikTok have built substantial followings by serializing these stories in short-form video. One format that keeps reappearing involves someone staring directly into the camera and narrating their alternate life in past tense, as though recounting actual memories. The comments sections on these videos are something else — full of people sharing their own divergence points, the moments where they feel their timeline split from the version they'd imagined for themselves.

The Psychology of the Unlived Draft

Psychologists who study narrative identity — the idea that humans construct a coherent sense of self through the stories we tell about our lives — find this trend genuinely interesting, if a little complicated.

The act of writing a detailed alternate autobiography forces a person to articulate what they actually value, what they regret, and what kind of life they believe would have made them happy. That's not nothing. Therapists have used similar exercises for decades: imagine you'd made a different choice, describe how your life unfolds, notice what feelings come up. The multiverse memoir is essentially that exercise, dressed up in genre clothing and posted for an audience.

But the audience part matters. There's a meaningful difference between journaling about your alternate self in private and publishing that narrative online. When you share it, you're inviting others to engage with a version of you that never existed as though it were real — and your followers may start to relate to that fictional self as meaningfully as they relate to the actual you.

Some creators report feeling more understood through their alternate-self writing than through anything they've posted about their actual lives. Which is either a profound insight into how storytelling unlocks emotional truth, or a slightly alarming sign that the fictional version is winning.

The Books Are Actually Arriving

This isn't just a social media phenomenon. A small but growing number of authors are bringing the format to long-form publishing. These books occupy a genuinely strange genre space — they're not quite autofiction, not quite speculative fiction, not quite memoir. Booksellers don't quite know where to shelve them. Readers don't entirely know how to review them.

One approach that's gaining traction is the dual-narrative structure: the author's actual life running alongside the alternate version, with the two threads commenting on each other. The tension between what happened and what could have happened becomes the engine of the book. It's a structure that owes something to literary fiction, something to parallel-universe sci-fi, and something to the kind of deeply personal essays that platforms like The Cut and Longreads have made mainstream.

The challenge for these authors is credibility — not factual credibility, which is obviously off the table, but emotional credibility. Readers need to believe that this alternate life could have been real, that the choices and consequences feel genuinely human. The worldbuilding has to be invisible. You can't feel the scaffolding.

Why Now?

It's worth asking why this specific form of creative expression is catching on in this specific cultural moment. A few threads seem worth pulling.

First, there's the broader mainstreaming of multiverse theory as a cultural concept. After years of Marvel films, prestige TV, and pop-science explainers, the idea of branching timelines has become a default mental model for a huge chunk of the American public. People who couldn't tell you anything about Hugh Everett's many-worlds interpretation can still instantly grasp the emotional logic of "in another universe, I made a different choice."

Second, there's the pandemic's lingering effect on how people think about their own timelines. Millions of Americans experienced a period where their expected life trajectory — career, relationships, geography, milestones — got disrupted or derailed. The alternate self who didn't live through that disruption is easy to imagine and hard to stop thinking about.

Third, and maybe most interestingly, there's something about social media's relationship with identity that makes this format feel natural. Online, people have always performed curated versions of themselves. The multiverse memoir just makes that performance explicit and turns it into art.

The Risk Nobody Talks About

Here's the part that should probably give us pause. Narrative psychologists will tell you that the stories we tell about ourselves shape how we experience our actual lives. Spend enough time inhabiting an alternate self — writing her voice, imagining her choices, receiving emotional validation from an audience who connects with her story — and the relationship between that fictional self and your real one gets complicated.

It's not quite dissociation. It's more like... competitive autobiographies. Your actual life and your fictional life start generating separate but parallel senses of meaning, and at some point you have to decide which narrative you're actually living.

Creators who've been doing this for a while often describe a moment of reckoning — usually around the time their alternate self's story reaches a point that their real self never will. The fictional version got the career, the relationship, the city. What do you do with that? Do you let the story end? Do you keep writing? Do you start trying to close the gap between the two timelines?

That last instinct — using the alternate memoir as a blueprint for actual change — might be the most interesting outcome of all. A few creators have described their fictional autobiographies as a kind of manifesto for the life they're now actively trying to build. The alternate self becomes a target rather than an escape.

A Genre That's Still Figuring Itself Out

The multiverse memoir doesn't have established rules yet. It doesn't have a canon, a community consensus on form, or a clear critical framework. That's actually part of what makes it exciting from a worldbuilding perspective — this is a genre in the wild, being invented in real time by people who are mostly just trying to process something true through the tools that feel available to them.

At 9ineverse, we spend a lot of time thinking about how speculative frameworks reshape the way people understand themselves and their stories. The multiverse memoir is one of the more unexpected places that's showing up — not in a movie theater or a novel with a rocket ship on the cover, but in someone's Substack at 1am, narrating the life of a self who said yes when she actually said no.

That's a kind of worldbuilding too. Maybe the most personal kind there is.
