I suspect most humans are like that, to varying degrees, and in various aspects.

As a random example, a co-worker showed me his very expensive fountain pen. That prompted a memory -- after having completely forgotten for at least twenty years -- that in high school I exclusively used cartridge-based fountain pens! That aspect of my life just *poof* vanished from my memory when I switched to felt-tip pens, and was suddenly swapped back in from an archive tape when I saw a fountain pen in front of me.

This wasn't a small detail of my life! My father got me those pens. They were German-made and he was very proud that he found them at absurdly low prices at a garage sale compared to their real value. I had to buy the cartridges, and they were hard to find. I had a special resealable container to contain leaks. I was proud of the dramatic improvement in penmanship this enabled. Etc, etc...

Just gone. Absolutely vanished. If you had asked me randomly if I ever used fountain pens, I would have said "no". It wasn't until I physically picked one up that it all came flooding back.

PS: I remember maybe a dozen things about my childhood apartment and its surrounds that I grew up in. Don't feel bad!
