In a dream I had, something interesting happened. This one guy in it was saying a sentence, and the last word (a noun) was blank, but it triggered in my head that
1: He did say a word
2: It was a word for "Malibu" (The beach neighborhood on the west coast of the US).

I am pretty sure there is no other word for malibu, and certain that he did in fact skip a word. But is it regular to have a memory triggered by nothing like that?
