Hey, that kinda sounds like Doc in Back To The Future II. When he says (something like) "Meeting her future self could create a paradox that will destroy the entire universe... Or... she could just pass out from the emotion."
Of course, it could be why our memories are so awful. It might be damaging to the brain if we had to keep track of all the random universes we interact with during our lifetimes. Not to mention the effect it might have on our psyche.
For years, I thought Larry Niven was dead. And it said the Lion shall lie down with the lamb--it turns out--it was the Wolf https://kingsenglish.info/2011/05/26/the-lion-shall-lie-down-with-the-lamb/
of course. It makes more sense if it's a wolf and a lamb. With a lion it would be more like a gazelle. Ask Archer, he knows a thing or two about gazelles.
An incident that occured to me....: Many decades ago, when I was about 7 (about 1975), a house only 6 months old that was next to our property burned. I remember the lady living there, and I remember the house, but I do not remember the house being built. Once that struck me as odd, I asked a few of the older people who lived down that road if they remembered it being built, and none could, though they remember it burning.
I remember people after the fire saying the house was only six months old and must have had bad wiring. But screw me if I could find anyone in 2010 who actually remembered the house being built... and I asked several people.
So you're saying they didn't remember the house being built... 35 years after the fact? I refer you to @BillJ 's post above.
Coincidentally, that's the kind of thing that happens on Bewitched, the show where your screen name is from. I remember specifically an episode where they kept making a house appear and disappear.
Yes, I do have a very good memory in general. It's a family trait. My mother would take a textbook to verify if I had learned my lesson and afterward she often knew the lesson as well as I did. It was amazing since being from another country she had never learned these lessons before.
It's actually quite common to walk through a city you're familiar with, see a new building, and think "Wtf was it that used to sit there ?" or something like that
Well, I've lived in a big city for years (before I moved to the countryside) and there are parts of the city where I wouldn't go for months, so if I saw some new building there, it wouldn't surprise me. However, I am sure I would have noticed if a new house would have suddenly appeared someplace that I would go by every day or so.
