Nothing really bizarre, but there are a lot of events that my friends and I remember differently. My dad wheedled me into riding Space Mountain with him when I was about 7 or 8, and we remember that very differently. They made me take my glasses off, so all I remember about the ride itself is black-with-neon-blurs and lots of wind, but I remember my being incredibly pissed afterwards and not talking to him for several hours, but his memory is that it only lasted a few minutes. Reality is probably in the middle, but who knows? We didn't bring the camera, which didn't do sound anyway. That's just the way human brains work.

I have had extremely vivid dreams that were plausible enough to make me wonder if they'd actually happened. The only one I remember is from last week, when I dreamed that I met Captain Sig from Deadliest Catch at a coffee shop in Homer and had a long conversation. In my dream he was a really nice guy. Showed me a lot of pictures of his grandkids. Logically, it doesn't make sense-- I've definitely been to Alaska, might have been to Homer, but I am 100% certain I've never met the man and would definitely not say anything past "I like your show." Still, it was realistic enough to leave me confused for a few minutes after I woke up. :)

You might want to look into the Mandela effect.

I distinctly remember going to a Japanese steak house when visiting Orlando about thirty-five years ago with my sister and her late husband (who lived there) and my (now-ex) wife. I remember the chef flipping a shrimp to my brother-in-law and him catching it in his mouth. Some years later (but while the relationships were still unchanged), all the other participants denied this ever happened.

Maybe you are being gaslighted??

I would have said this had never happened to me, until just now, where I spent the better part of an hour looking through a listing of my state's historical highway markers, trying to find one specific one.

I KNOW it exists. I drove past it twice a week for several months straight, often stopped at a stoplight right next to it. I KNOW it's there.

...yet, according to the state's listing of markers, I'm hallucinating. /headdesk

Exactly. I'm not talking about years to forget in. I'm talking about within a few weeks.

While I might be crazy, it is strange that it is only specific things that have changed and rarely at that.

Rewinding a "failed" plane takeoff was the first I remember.
I could see the runway behind us, and then it was not and we were able to land.
Good I looked away for a second I suppose.

So far the desk has been the most undoubted, for me anyway.
A hour of my life rewritten for no apparent reason.

Now that sounds like your scriptwriter decided to do an edit but forgot to properly erase the character's (yours) memory.  ;-)

In the inimitable words of Rick James:

"Cocaine's a helluva drug."

Have you been programming a quantum computer lately?

I have wondered how possible that is.
According to science there are multiple dimensions and it is difficult to know what that "looks" like.

Rely on it being a lot less possible than someone or someone's friends being mistaken, or those friends being mildly malicious.

Likewise carbon monoxide poisoning and malnutrition can cause un-events that sound much like those described, and visions, which can be of anything (William Blake seeing angels in his pantry, for instance) respectively.

I mean, I occasionally dream 1-5 second, useless scraps of my future, presumably due to probabilities aligning in the exact way my brain thinks they will, but when things have already happened, that's your brain doing something strange, and worth getting a medical opinion on. Or a carbon monoxide detector. The number of hauntings that have turned out to be low-level CO₁ poisoning...

Exactly. It is really disturbing how many people are treating this lightly. What OP described isn’t just daydreaming but a serious detachment from reality. Could be any number of things but most of them are pretty serious and some of the are fixable or thins that it is important to be aware of.

All this BS about alternate reality or timelines is fun to speculate on when someone’s health and well-being aren’t on the line.

Since mine was the first 'light-treatment' post, I'll weigh back in.

If it's just the odd occasion, you can probably afford to dismiss it as 'one of those things', an anti-deja-vu experience or a forgotten dream. We all have a gauge of how often weird things happen.

But I agree, if it's happening 'frequently' (whatever that means for you), or increasingly frequently, talk to a professional - just in case it's something serious that can be caught early.

There you go, that's my social responsibility assuaged for today. :)

I must thanks everyone for their concern.

It is likely that the abrupt turns in world events at occurred at the same time are a coincidence and unrelated.

In reply to praguepride (msg # 18):

Well, from no more than a handwriting sample it's difficult to make an accurate diagnosis.  Best not be too serious about it from that perspective.

However, if we must be serious, I'd say this could be a symptom of overwork, advancing age, chronic fatigue, onset of Alzheimer's Disease or dementia, an effect of stress, lack of sleep, or too many of the wrong kind of prescription medications, or any of several other conditions.  I don't know the o-p well enough to be any kind of credible judge.

Best not to set too much store in it unless it is a recurrent thing, or it really is that worrying.

As one whose short-term memory fails him on a regular basis, I get where this could be of some concern, but I'm not a medical practitioner so I'm not going to go much further than I already have in venturing possible diagnoses.

What concerned me wasn't just short-term memories but as he described it "rewinding time". Making a table and giving it to someone only for the table to appear differently isn't the same as forgetting your address or a close one's name. Witnessing something that didn't happen is very different than memory lapse.

From the OP's description is sounded more like visual hallucinations instead of memory issues which is why I was concerned as hallucinations, while they can be linked to simple things like stress or exhaustion could also be linked to anything from CO poisoning to mental illness to physical brain disorders.

I am not a medical practitioner nor am I trying to diagnose something but instead just raising awareness that as horus mentioned, if this is a reoccurring then it is worthwhile checking in with a doctor. Better to find out it's nothing then years from now finding out it is something big that could have been prevented.

My rule of thumb?

Don't go online for serious advice. Go to a serious professional.

Wasn't looking for "advice" just wondering if others have had like experiences.
I have to assume that is no.
Or, that they don't want to talk about them because of the most common reaction shown here.

Oh, if that's what you want, yeah, I get this all the time. Sometimes it's me, sometimes it's someone else. But, honestly, sometimes I'm just wrong. No matter how vivid my memory or how stark the contrast between what I believe I saw and the prevailing evidence, at the end of the day we're all just human. We can justify treating other humans like property. We can deny any truth we find uncomfortable. We can hear disembodied voices and do what they tell us. We can have multiple entities existing in a single physical unit.
Sounds to me like a little memory glitch is to be expected. Heck, the earth is bombarded by energies from a gigantic nuclear furnace so what are the odds a stray high-energy alpha didn't bounce off your noggin and change a path or two?

I can maybe count on one hand the number of "I could have sworn X happened..." incidents of that lucidity level that I've had in my life (not counting "I could have sworn I left my keys on here" types, which are a whole lot more common.)

I can't actually recall any of the incidents now. I forget a lot these days, or maybe, once I filed them as 'false memories' I automatically repressed them.

Or maybe I've never had any such memories, but I'm sure I did...

In reply to icosahedron152 (msg # 26):

Yes, they are thankfully rare as they are hard to accept.
They really make you wonder WHY as in themselves they are not important changes.

Memory is a very complicated thing. Studies have shown that every time you access a memory it becomes fluid again, changing based upon your current state.

As for a rare occurrence it is probably just a transcription error. The brain isn't perfect and given the sheer volume of memories that your brains is processing on a daily basis even 99.999% accuracy is going to have some blips.

Finally there are numerous causes of hallucinations as discussed above ranging from gas poisoning to drugs to brain cancer to chemical imbalances.

I've had this happen more often as I get older.  It's a short-term memory kind of thang for me.

Way back when I was still in my twenties I did have a couple of waking dreams during a period of extreme stress.  They both turned out to be prophetic.  (If only I'd listened!)

I'm not talking about a "how did my keys get here" type of thing.
I'm talking about a "spending several hours putting something together" type of thing.
