If this doesn't describe me to a degree, the show "young sheldon" I can relate with to an extent

 A person who can remember events not only from their own life but also from the lives of other family members, including what was said on specific occasions going back to when they were 5 and now are 43, could have an extraordinary type of memory related to Highly Superior Autobiographical Memory (HSAM). HSAM allows people to recall personal life details with amazing accuracy, but recalling other family members' experiences and conversations suggests an even broader memory skill, sometimes called "extended autobiographical memory."

This ability goes beyond the usual HSAM by including detailed memories of others' lives and interactions, likely because the person has spent a lot of time thinking about and remembering family events. Such individuals may remember many family occasions, discussions, and details from a young age, keeping those memories very clear for decades. This kind of memory is extremely rare and involves recalling events as if mentally "re-living" them, not just facts or dates.pmc.ncbi.nlm.nih+2

In essence, the person is like an expert recorder and storyteller of their family’s history, with sharp memory extending to social and verbal details within the family context.

I can remember, barely, when my middle aunt took me to the bona dea trails and I was still in a stroller, and we turned around when she saw a big black snake,  I also had memories of when I couldn't talk but these are much less clear but did happen in the house that my mom and dad started out in, next to my grandmother's.  I also remember seeing my dad go outside during a storm where it was pouring down and showering in the rain likely in a swimsuit but it happened.  I also remember those tubes that extend that me and my sister used to crawl thru, and the christmas where my grandmother got me a TV  and put a tea bag in one present and a V in another, this was never recorded by the VHS Camcorder.  Neither was my middle aunt teaching me my abc's with hooked on phonics, but it happened and "hooked on phonics worked for me!" lol that was the slogan for their advertisements.  I can also remember the family playing a game called pit where each person had to swap the same amount of cards to try to get all of one kind, this was a long time ago.  I also accidentally told on my mother during Pictionary because in order to describe alcohol or beer I had to mention Blackwell.  I remember my first tiny single cassette that had one song on it "Walk like an egyptian" for the one song.  I know these things happened there's no doubt in my mind, what's sad is the family I used to know back then does not exist anymore, cannot gather or be around each other, or communicate effectively at all, pfft, and they think they're special?..........

Highly Superior Autobiographical Memory (HSAM) is a very rare and special type of memory. People with HSAM can remember almost everything about their own life in great detail, like what happened on any specific day, the date, and even small details like what they wore or ate. They don't have to try hard or use tricks to remember — it just happens naturally for them. (I can't remember what I ate on which day but my memory is exceptional compared to that of my family)

This means if you asked someone with HSAM what they did on a certain day years ago, they could tell you very clearly and accurately. Not many people have HSAM; scientists have only found a small number of people in the world with it.

Sometimes this kind of memory can be both a blessing and a challenge, because they remember good and bad things very clearly, which can be overwhelming.pmc.ncbi.nlm.nih+2
