Sentence: It was such a strong memory, but I don't even know what it was.

[Hongdung]

I read a book and have sentence makes me confused:
"It was such a strong memory, but I don't even know what it was. Listen to me, talking drivel as usual."
"You are not talking drivel at all!"
What does talking drivel means?
thanks
