No phenomenon excites me more than waking up. Nothing tends to produce a more extraordinary idea of…everything, than this autogenesis — This beginning of what has been — which itself has its beginning = What is, — and that is all shock, amazement, contrast. As a result, a state of equidifference occurs as if…there were a moment (extremely fragile) in which you are not yet the person that you are, and you could come back to life as someone else!! A different memory would develop. Whence fantasy — the external individual unchanged, and the whole psyche replaced by another…!
— Paul Valéry, Cahiers / Notebooks 3
Been there, done that. It never gets old for me. Every morning, consciousness returns before the person quite does. Memory restores the name, the history, the attachments, the unfinished business. Within seconds the seam disappears and we say: I woke up.
Perhaps memory is the nearest thing we have to a personal essence. Infancy suggests as much from one direction. Logically, I know I suffered, feared, and was comforted as a baby, but I remember none of it. Those first few years belong to my biography almost as though they happened to someone else. Dementia approaches the same condition from the other end: consciousness may remain after much of the remembered person has vanished. Eventually others can remember your life better than you can.
Death ordinarily hides the distinction because body, consciousness, and memory usually expire together. Imagine, then, being offered immortality on different terms. You may live forever, but every so often you will go to sleep and wake without a single memory. A new personality will form, live for decades, and in turn be erased. The cycle will continue eternally.
Would you accept? Probably not. What most of us want preserved is not consciousness in the abstract but this accumulated life: these people, these memories, this particular past. An immortal succession of amnesiacs sounds less like eternal life than endlessly repeated death. And yet infancy presents the puzzle in reverse. We readily say that the memoryless child was me, while recoiling from the idea that a future memoryless consciousness could also be me.
But there’s no reason to make this an entirely serious thought experiment. Comedy is as much the stuff of life as anything else. I can easily envision this as a warehouse snafu from my own experience. Picture it:
Two people fall asleep at 11:17. During sleep, whatever process normally returns yesterday’s memories to the correct waking consciousness routes them incorrectly. At 6:42 the next morning:
“Why am I in this house?”
“Who is this woman?”
“Why do I apparently know how to drive a tractor-trailer?”
“Why do I have seventeen years of memories of being married to some guy named Dennis?”
If you swap autobiographical memory only, the body retains procedural knowledge. So the concert pianist wakes with the truck driver’s childhood and marriage but discovers that her fingers can still play Chopin. The truck driver remembers conservatory training in exquisite detail but can’t make his hands perform it. Each possesses somebody else’s explanation of skills that remain physically lodged elsewhere. Emotional residue could make it stranger still. You wake with no memory of your wife, yet her presence produces an inexplicable feeling of safety. Or you remember being desperately in love with someone else’s husband while your own nervous system recoils from him because it has never met him.
Everyone spends the first half of the story insisting, “I am obviously the person whose memories I have.” Then somebody asks, “But if his memories are in your brain and your memories are in his, which one of you is actually you?” And both reply: “Jesus Christ, not now.”
I could see this being something like Monsters, Inc. rather than Freaky Friday. The comedy lies in the collision between the sacredness of personal identity and the banality of inventory control. Sleep already has a vast, hidden logistical infrastructure, and most nights it works so efficiently nobody notices. Memories are processed, sorted, tagged, and returned before waking. Dreams are damaged packaging. Déjà vu is a duplicate shipment. That thing where you walk into a room and forget why you’re there is a partial pick error. Then one morning somebody opens the wrong carton. The person wakes up in the correct body. Name on the outside is right. Address is right. But the contents don’t match the manifest.
“Package says Robert Ellis.”
“Yeah.”
“Body says Robert Ellis.”
“Yeah.”
“Memories are for Angela Martinez.”
“Shit. Check the invoice.”
Two clerks start frantically pulling records, comparing timestamps, discovering that Robert and Angela entered REM sleep within three seconds of each other and somebody scanned the wrong tote. Meanwhile both humans are already awake and wrecking each other’s lives.
As usual, I’m just giving away great ideas for free here.
