I one heard a NT complain and wish that they had a super photographic memory, I told them to be careful what you wish for. You could end up with a photographic memory packed with rubbish (childrens cartoons) and nasty things such as breaking up with your partner.
Vivid memories of painful and traumatic things is typical of human memory in general. It's an evolutionary imperative for our brains to vividly recall things that us hurt. But it can be heighten if you have a pre-existing anxiety disorder, like PTSD, or if the experience was traumatic enough to induce PTSD.
I have PTSD, so I know what I'm talking about here.
I also have eidetic or "photographic" memory. Eidetic memory isn't about having good long-term memory--these are two different things. Actually my long-term memory kind of sucks, like most people with eidetic memory. Eidetic memory is about how you brain intakes information in abundant amounts at one time and arranges it in your short-term memory in a more linear way than other people, so you can recall it back in a seemingly "photographic" way. But the amount that gets stores into long-term memory after that is about the same as any person without eidetic memory.
Lots of people can remember childhood experiences like cartoons in relatively precise details--I am not one of them. Because of eidetic memory, my brain is constantly trying to take in more information than it can store long-term, and consequently, as newer memories are formed, I can lose older ones, unless I make an effort to retain those memories. Much of my memories of childhood are a vague blur now, while my brother who doesn't have eidetic memory can still readily recall things like cartoons and TV shows both he and I watched regularly as kids. Yet give me a map and I can look at it a few minutes and be able to redraw it quite accurately for a short time afterward. But after about an 1 hour, especially if I'm doing other things, my detailed memory of the map will fade rapidly.
To be truthful, eidetic memory is kind of useless. It helped me a lot in school because I could cram a hour before a test and then ace the test, but in the "real" life it's more of a nuisance than anything. And that it contributes to the degradation of my long term memories doesn't help.
