Like many people, I have a few early memories (3.5, 4 yrs old). But I can't stop wondering - do I really remember them, or do I only remember remembering them?

Like many people, I have a few early memories (3.5, 4 yrs old). But I can't stop wondering - do I really remember them, or do I only remember remembering them? I mean, is it a "direct" memory? Or is it an act of recollecting a previous recollection of it? Like, I remembered what I did at 4 when I was 6, fine. And then, if I happened to remember it still when I was 8, I actually remembered how I recalled the event being 6. This is (I believe) how distortions gradually crawl in. And I believe it persists in adult life as well; every refreshing of a memory is actually rewriting it, thus damaging it in a way
