This fascinates me. No one has an answer for my question: when we recall a long forgotten memory, where was it? And the related questions: Why did it get triggered by (a conversation, book, or something else)? How did my brain retrieve it? How did it get 'stored' in the first place?

Even Google's AI chat bot Bard could not tell me, though it had a lot to say in general.

I think that I shall never know
How memories come
And where they go.
