A brief visit to another timeline

Here’s a weird experience I had some years back. I wonder if others would have had a different train of thought.

Our Allen Center lab is on the third floor, and right across the hallway from it is a conference room where we often have meetings. One day, we were having a meeting. It was a long one, several hours, and very intense, with a few folks from outside our group. I had been more tired than usual going in anyway, and pretty drained by the end. I was gathering my laptop and papers and was the last one out of the door. Everyone had gone by the time I got up and went out of the room.

I did what I always do after those meetings, which is walk across the hall and swipe my ID card to get into the lab, all on autopilot, while still thinking of the problems we had been discussing. Or, rather, that’s what I tried to do. What I realized, to my complete befuddlement is that there was no swipe reader. In fact, there was no door at all. Where the entrance to my lab used to be, was a totally blank wall. No Allen Center sign, no door, nothing – just smooth white wall. I stood there, running my hands up and down the wall, to make sure. I paced back and forth a bit, hoping the perspective change would un-glitch the universe – nope, no dice.

I better explain right now that this was not actually a paranormal situation (nor was I on any kind of exogenous psychedelic). What happened was that, counter to the hundreds of times we’ve done it in the past, we had had this meeting on the 2nd floor instead. Right before it started, someone had grabbed me and led me down to the 2nd floor conference room while talking about something intriguing, and I managed to forget all about this slight but crucial change of venue. The problem is that the 2nd floor is just like the third, in almost all ways: same layout, same furniture, same conference room, same whiteboards on the same walls. The only difference is – where my lab is located, the 2nd floor had shell space which was walled off at the time.

The whole episode lasted probably about 20-30 seconds total, but it was long enough that I had a long train of thought, which I carefully dissected later (after my cortisol had stabilized) because I thought it was interesting. It went something like this. First, wtf is going on – where’s the lab? Then: ok there’s no lab, that much is clear, let’s move on from that basis. Now, I’ve read enough science fiction about people ending up in some parallel timeline that this wasn’t “impossible”, in the largest sense of impossible, but it certainly had implications. If there was no lab here, a) is it somewhere else, or b) was there really never any Levin lab at all?! If (a), how do I find it?! I supposed I could call the university main number and pretend to be an outsider needing directions to the Levin lab. Finding it, even elsewhere, ought to at least close the gap a little.

But what if it’s worse than that – if option (b) is the situation, then where do I go next – what do I actually do here, if there’s no lab? A quick glance at my Macbook laptop, and the obvious realization that this building is only a few years old, dispelled my first guess that I’m still an undergrad at Tufts and the last 30+ years have been a dream. No, definitely it’s not still 1990. But if it was, I think I’d have adjusted pretty quickly. It was weird, but not to the point that I was going to freak out and grab anyone by the lapels while babbling incoherently, and end up arrested. I’m pretty sure I’d make a few careful probes into what the current deal was and then just get on with the climb (perhaps wondering if any of the 30 years’ worth of information from my career “dream”, which I could remember vividly, would actually be useful this time around and perhaps save me some headaches and dead ends).

But that train of thought reminded me of how tenuous the grip on a specific life story really is; I really was pretty prepared to find out that it had all been a dream. Actually, a few times a month, it hits me anyway – I step back, mentally, and just pause in complete wonder at my incredible good fortune. It’s easy for me to re-capture the feeling of being a fairly young kid, finding out for the first time what a scientist is supposed to do, and wondering – is it possible, that someday, I could actually do this? The improbable, wild, whole truth of it – the fact that there is a lab here, full of amazing people doing awesome things to answer questions that keep me up at night, doesn’t seem very real to me at all, much of the time.

So the whole life story was pretty plastic. But oddly, what wasn’t plastic, is the realization that I’m almost certainly late for something. That part must be so deeply carved into my brain by now that no amount of reality bending was able to touch it, and standing around not doing anything useful felt wrong. I still had this nagging anxiety that whatever the situation, I had better resolve it right quick and get to where-ever I was actually supposed to be. What to do?! And that’s when I found out who my Keeper of the Ground Truth is, at least in this engineering building: my good friend and long-time collaborator David Kaplan, who often visits me in this building. Because, that was my next thought: I’ll go see David and ask him what he thought of the world and my place in it. It never occurred to me for a minute that he may say “Who the devil are you?”. My mind had assumed, apparently, that whatever happened to me couldn’t have possibly affected our knowledge of each other. And that’s what broke the case wide open: as soon as I made a plan to go find him, I thought of the stairs and corridor I would have to take, and that’s when time started moving again, the representational geometry of my surroundings kicked in, and I realized DUH – I was on the 2nd floor…

That whole episode lasted no more than half a minute, but it felt like much longer. Going back over my thoughts later, it was interesting to see how such a weird scenario would play out and the thoughts that flowed during it. What would your thoughts be, in my place? Do you know?

    “No, definitely it’s not still 1990. But if it was, I think I’d have adjusted pretty quickly.…” I think “selves” all adjust pretty quickly (constantly), it’s just rare that they know it. Thanks for sharing this. 🙏

    I had something similar. I had been travelling a fair bit prior to a full time move to Shanghai back in 2007. When I finally did move to Shanghai, my first few nights were going to be in a hotel before I moved into my apartment. I went to sleep on the first night and woke up in the middle of the night, completely disorientated by where I was and what I was staring at in this room. It took a full minute or two before I realised I was actually in a hotel room in Shanghai. Still sticks with me to this day.

      This relationship with the room you wake up in is the thread that runs through Marcel Proust’s In Search of Lost Time. This brings me back to his books, thank you 🙂

    I had a very memorable experience as a teen after an intense session of inhaling glue. The high produced an elaborate and vivid recall of various moments in my life, that almost felt like I was reliving them, though seemingly random memories that I didn’t at that age typically think to recall, or cherish in anyway, ie discarded contents from the life story. When I came to, I believed I was two years in the past and the last two years had not happened yet. I distinctly remember the mix feeling of loss of the lived two years coupled with the excitement that I could make slight alterations based on the information I had.
    Like you, it was a friend that helped repair the slippage in time. Relation is the ground truth.

    Both upon arising from deep dreaming, and when awake, but very tired, I will encounter memories or concept clusters that have been installed wholecloth amid the historically generated fabric of thought, and have to expunge or correct them. Once, closer in sensation to the anecdote in the post, I saw a person walking towards me along a path at night, and the particular outline of their silhouette in the dim light registered not merely as “not a human”, nor the simple negative “unknown”, but a distinctly positive imputation of “alien”. For ~15-30 seconds, I was convinced that the invasion had begun, and experienced an extended chain of automatic deduction and world model recalibration from this seemingly absurd premise, culminating in the conclusions that now was the time fight or flee. Fortunately, my resolve held, and I moved towards the sound of the guns, and the phantasm resolved into a old woman, hunched forward, wearing a bulky jacket. The systems of the world re-acquired their previous configurations and values, leaving only the mental shadow of alternate Weltanshauung, and a new understanding of the automaticity with which dramatic revisions of the same can occur – I observed a very high learning rate during that particular run of the backpropagation algorithm.

    You know, this made me want to try to put into words a type of phenomenon I frequently experience (perhaps trivial) but a caveat beforehand: I frequently do not ‘experience’ memories, at least, not the way most people do. I simply remember aspects of my life as narrative facts, often conntected by associative semantics as opposed to an episodic experience (which is what most people seem to describe remembering as).

    Anyway, very often I might have a stimulus, often auditory or olfactory (these tend to be my strongest, visual does very little for me I find), and all of a sudden I find myself transported back to a specific instance or ‘anchor’ in a personal timeline strongly associated with that stimuli. Hence my caveat, since this is a very novel experience given the context.

    Now, I don’t really experience much beyond simple somatosensory temporal feeling of ‘you’re here in this place in your memory right now, remember this?’ and it’s such a strong vivid feeling of ‘going back’. It’s like specific memory anchors exist (like system restore points? or checkpoints), and they’re often core memories too. For example, if I ever have doubt about a personal narrative, I think to a core memory and trace a chronology to the incident I need. But the experiences themselves, usually just instantiate by themselves. However I’ve been trying to trigger them on my own because they help quite a lot when I feel like I’m stuck in a rut or tunnel visioning on a present situation. Like a perspective shift. They’re rarely distressing though, and often pleasant, closest thing to eudaimonia that I can think of that I’ve experienced.

    In the event of a ‘real’ temporal shift, I think I might be a little distressed, especially at the idea of having to redo a timeline after discerning the where/when, but it might be interesting. A replay (like a new game+ save) with existing know-how. But like you, it leaves me wondering about how temporally plastic your sense of self is.

    I imagine the causality aspect of memory would favour temporal plasticity, especially when it comes to psychologically probing counterfactuals in decision-making. But I’m also reminded of a theory of why memories are deliberately low-fidelity(?) to aid with discerning reality from the past. I wonder about folks with very a vivid and imaginative somatosensorium, would they be more likely to have an easier time ‘slipping’ into a memory given that much of recall is actually reconstruction with a stochastic element of imagination to fill in gaps in fidelity.

    Wow, thank you, loved your sharing, Mike. Turn it into a sci-fi novel or at least a short story. 🙂

    I’ve had a similar experience having pressed the wrong floor number of my building while being distracted, getting to “my” door, only to have the key not fit, the door look oddly familiar yet oddly unfamiliar, before realizing what had happened.

    Fortunately no one has opened to door coming out while I have been trying to go in. 🙂

    Been there! And you have said (or someone you were in discussion with recently — was it Bernardo Kastrup?), memory is mutable, and maybe it’s always mutating every time we access it, including additions and omissions.
    Funny and fascinating, though, how your intellect immediately went apeshit, desperately trying to reconstruct a model of the universe that fit the memory you had access to, all within less than a minute.

    This story reminds me of the interesting observation that very little “basic knowledge” seems “built-in”. The brain is neither born with, nor naturally develops as part of a genetic program, knowledge about basic physics, motor skills, emotions, or even concepts like object permanence. Babies have to act as little scientists, constructing hypotheses and testing their predictions against real-world data—though they’re terrible at writing grant applications, and usually leave their labs an absolute mess.

    A great deal of twentieth-century theorizing about cognition assumed the opposite: most knowledge is programmed in as some reflex, instinct, or hardwired behavior. It seems to me that this presumption is starting to collapse as scientists are discovering more and more ways as to how consistent patterns in complex behavior can emerge without being preprogrammed into cognitive software uploaded from the genes.

    One major advantage of not having everything preprogrammed is that it leaves you far more flexible in the face of the unexpected: If you *did* find yourself shunted into some parallel timeline, it would not be good for your genes if you were built to be unable to accept this fact.

      yep; this: https://www.mdpi.com/1099-4300/26/6/481 (and more coming) addresses that kind of on-the-fly interpretation and emergence of meaning, and the resulting plasticity to the unexpected.

    This is very good closure to the frustration I felt when Michael Pollan asked you “But how do you get up in the morning if you don’t have a self?”

    I can’t wait to see what his conversation with Bernardo did to his mind.

    Cheers

    I have the converse happen all the time. I’ll wake up thinking that I’ll get ready to go prep my lecture notes and start work at my lab (Health Education Action Lab), only to realize that I really did jump to a timeline where I am on leave, taking care of two kids with a terminal illness. I wonder whether an adjacent universe exists where I will get to do academic research again, or whether that is just a fantasy. It seems like another life. And I need to accept this one. Wholeheartedly. But your thoughts helped me realize how absurd (and wonderful) waking up into any timeline can be. And I so hope this is the timeline where your lab facilitates the breakthroughs that will make anthrobots that crawl around and mend my daughters’ lungs and GI tracts a reality. I can see them in my minds eye, meandering around recruiting cells to team up and build better than the typos in our genetic code have allowed. Maybe then they and I will breath (and grow) easier. I can and do hope for that kind of a future. Thanks for giving families like ours hope, Dr. Levin.

      Thank you for sharing. Words fail in such situations; I’m so sorry. Many people, and we, are working on these kinds of things. I believe solutions will come; I too can see them in my mind’s eye.

    As an aphantasic with a very strong but unreliable sense of direction, I find myself forcing the evidence to fit my incorrect assumption, eg that we’re travelling north when we’re headed south.

    I think about this scenario quite a bit as I take Philip K. Dick and his eventful life seriously. “Time out of Joint” was one such a story by him. Thank you for sharing.

    Given that I believe in an ontic computationalism framework, it seems eminently plausible if the simulation hypothesis is correct.

    Tiredness lends itself to reduced consciousness. Having said that tiredness is a pathway to an increase in the subconscious. Both are information and in the right combination can effect experience as well as having the ability in of transgressing the known laws of physics. The effects usually are small but can in extreme cases be significant and transgress the known laws of physics. I do not believe in the paranormal but I do believe in the limits of our knowledge and mankind seeking false comfort in the security of his knowledge.

    The ability to get lost is not a failure of navigation, it is a success of navigation.

    I love that your work asks me to get lost in unfamiliar places, to let go of tenuous grasps on stories, at least for a short awhile. Your work and your stories inspire me to be less afraid of uncertainty, which is about as good of a navigational tool as one can have.

    That is a good story for the approach of the summer solstice, where a lot of “day” gets packed into a day, within our perception of a “day” as being daylight hours.
    Probably I would have done something similar. After my degree, for about two years I would sometimes believe that the whole degree experience was in my imagination. I would go to my degree certificate, for evidence that it had really happened. It took about two years before it occurred to me, in those moments, to look at photos from my university times. When I began looking at photos of friends and fun, the phenomenon soon stopped happening.
    So it seems that I have a similar tendency to focus on the concrete, the formal and administrative at first (walls and card swipes, and certificates), and it was by thinking about friends that my own situation resolved too.

    Yessir, exact same thing had happened to me. My lab is on 3rd floor and I was baffled why I couldn’t find it on the 2nd floor 🤦‍♂️.

    I’ve also had a separate incident where I had deja vu that lasted 1-2h (normally it’s only a fraction of a sec for me), but it felt like a lifetime. I was so distraught because I thought I was trapped in time.

    I’m 80, retired from a tier 2 research university, English department. I was hired in 1971 to teach creative writing. It was a strange Department–dull tired folks, who never had an idea, and bright, off-beats, who didn’t really fit into an English department and perhaps not into academia. An academic battle broke out so heated and ugly that it was noted in The Chronicle of Higher Education. The group that I belonged to proposed to secede from the English department and create a program in Writing Studies. It was a time when many people in the humanities realized that their disciplines had mostly lost their ways. One of my colleagues and I wrote a manifesto in which we argued that, in a time of explosive cultural change, literary studies– the passive reception and interpretation of a largely fixed canon of texts– was quite pointless. Writing studies would focus on the dynamics of literature and the practice of writing. It was intense. Some of my colleagues found boxes of rat poison in their mailboxes. It was, to be sure, an attempted takeover. We left the traditional department with nothing to do. It was awful, compelling, and mostly pointless as many academic battles are. I had a few psychological mishaps, including one precisely because we had a meeting in an unusual place and for a brief time I thought my office had disappeared. I don’t remember the details. This was 25 years ago, but be careful. I had a minor heart attack. I see parallels between what we were doing and your work. We might have used some of the passages you quote from James in our manifesto.
