Yes but it could be the opposite as well- you could remember specific details very well bc they stick out in your mind, whereas general details might be harder to keep real and intact.

There isn't really one true answer for something like this. It will be different from person to person, and even for one specific person it will be different memory to memory.

I do think though that if you have one outstanding experience, that you can hold onto the feeling you have from it (whether consciously or not), and remember and be able to access that feeling for a long long time. And even if you're not sure how accurate your memory is, that feeling will still be there.
