Dream in D Minor

Not of great interest: a scene in which I'm with musicians, playing bass, being taught this repetitive riff. It is in D minor, pentatonic based, a short motif that goes through minor variations. I hear it over and over and play along, but then decide to play long chords underneath the riff instead, first Bb, then C, etc. Someone is transcribing this and writes the chords as "Bb5" etc. I remember all the music on waking, but it is terribly boring.

There is another exciting sequence in a car, where I find someone who normally does not smoke, smoking a cigarette.
