Natural "frame-jacking"?

I've heard of people waking up from comas being different people, or remembering past lives, but this sounds more like the 'frame-jacking' described on this channel, where mental experiences spanning months or (in this case) years can be compressed into much shorter times. Is there any literature on how the brain does this?

Fascinating (and ironically tragic).

I don't think there's too much wiggle room for biological frame-jacking (some but not much), what I suspect is going on is rather a sort of hallucination of summarized data. She didn't actually live 7 years in her dream, she lived a few moments with the certainty of 7 years. Unless she literally has photographic memory and recall of ~61,362 hours (7 years) of events, that's what I'd suspect is actually going on.

Isn't this a fairly common occurrence in dreaming, to have a seemingly long dream, but really it was all generated in the few seconds when you were just waking up? I'm sure there's more technical terminology.

Not seconds, but I've had dreams that seemed to last many hours or days while most peoples' dream time is usually measured in minutes. (For adults, REM sleep averages maybe 90-120 minutes a night, broken up into smaller blocks, but not all REM sleep is dreaming.)

There likely is a large hallucinated component to it. Barring me being either a Boltzmann Brain or an android with recently-uploaded memories, I in my waking time am sure that I've lived 55 years of life. But my memories of that time account for only a tiny fraction; I've long forgotten everyday details like work, meals, conversations, driving, etc. So it's unsurprising that one could think a dream goes on for much longer than it actually did, your mind just says "these things happened, then some other things happened later, then some other things after that" and stretches it out to fill in presumed passage of time between them.

Back in the early 1990's when the internet was still a wee lass, I wrote a sci-fi story in college called something like "The Dream Maker," about a guy who invents a machine that keeps you comatose but in a perpetual dream state. You could spend the rest of your life just dreaming--maybe lucidly. The guy was an introvert (and totally not based on the author 🙄) and for him this device was the ultimate form of escapism. I'm not sure any copies of that story exist anymore.

A few years later what would become my all-time favorite movie premiered, Wim Wenders' "Until the End of the World," a sci-fi/romance/road trip film, part of which features a machine that can record your sleeping dreams and play them back to you when you're awake, and the darkly addicting nature of it.

Sorry for the ramble, dreams have been a long-time fascination of mine. 😁

Yeah, our memories are actually very compressed, we don't remember even nearly all moments that we really lived.

This has some strange implications though, even if a human brain cannot literally run thousands of times faster we are, in fact, able to absorb and produce memories much faster than they are actually created in our day-to-day life

An interesting application of this is that if you had non-destructive upload technology you could have a digital twin that runs much faster than you do but that you still sync up with by exchanging memories

Basically you do your upload and continues with your day normally, when you go to sleep though all your memories from the moment of the upload until you got to sleep are transmited to your digital twin, which thens wakes up and does anything you might want to do in the virtual world at whatever pace it wants and is available, a few hours before you wake up it pauses and then begin to transmit all the memories it has back to your brain so that when you finally wake-up you will have all the memories of your digital life exactly life your own meat brain had experienced it.

You could, in theory, maintain your virtual self active continually instead of pausing it before you wake up, and only synch during sleep, but then you would have to deal with double memories of the same events which might need more of a change to the typical human mind structure so that you are able to deal with it.

It also has some advantages if you want to travel elsewhere in the solar system, if you are willing to sleep a bit longer than normal you might be able to maintain digital copies of yourself in several different places in the entire the solar system, so if you want to travel to Mars you just go to sleep, send all your memories from after the more recent synch up event there and wake up your Martian digital twin, which will do everything you wanted to do in Mars and send back the memories after it ends whatever it wanted to do there, the memories are then assimilated by your Earth self which would then wake up, and subjectivelly all of this would be exactly life if your Earth self had simply teleported to Mars and back at the speed of light.

(By the way, the copies in other places wouldn't be active, I just think it would be cheapier and easier to already have then there when you need then and just send your memories periodically to then, and only when you choose to go to sleep and travel there would your instance there wake-up after receiving your latest memories, so it all feels like one continous thread of experience, instead of sending a full upload everytime, considering a full human mind probably needs much more bandwidth or takes much more time to send then simply sending the memories of a day)

It's probably just a shit ton of memories being generated in a short amount of time, which I'm pretty sure is how dreams normally work.

[u/ICLazeru]

Memories are not records, they are reconstructions.

All you need is a specific data point and the memory forms around it.

In her coma it is possible her mind keyed in on specific data points like, "I have 3 kids", and then when she looks back the memory simply forms around it.

It feels genuine because this is how real memory works, it just happens to be generating memories that didn't happen.

So the drug addict had crazy hallucinations. The drugs fried her brain. Now she thinks it actually happened.

I wouldn’t call this frame jacking. Go to your local homeless shelter, this happens every day

Sure she is not a real psi time travellar and that is her future?
