I was thinking about making a thread on that - and also on dream-dream memories.
I have both - I do rather often experience remembering something in my non-lucids.

Especially I remember prior dreams and their content - places and things - stories, background-stories to persons, even.
Like a dream-flat, which I only ever saw and lived in together with a certain group of up to 5 people in my dreams.
People, I know from real life - but in an other acontext than their real lives - sort of consistent over the dreams mostly, though.
And this flat was also pretty consistent - over several stories.

On another occasion I had made some small sculptures in one dream for an exhibition - in a dream some nights later - somebody had seen and liked them - and invited me into an art academy for a class. Beautiful dream.
I remembered the pieces in detail from several nights before - only from her mentioning them.

And then there are real-life memories - some more accurate - rather less so.
Once DCs told me, that a mountain lake close to the wells would have the name "Ringlake".
And I dreamt of remembering, that this would be correct, and that I had known that before.
This name does exist and belongs to a natural bay, which is almost separated from the main lake - not the imagined small one up there.
So - a mix.

Once I got lucid from seeing a house, which I knew was ripped down irl - dreamt of that house standing repeatedly without getting lucid afterwards unfortunately.
