Stevie songs that connect?

[Heartboy]

We all know Stevie's written butt loads of songs over the years and recorded alot of them as well. Either with the Mac or solo, my question is, what songs go together? Which songs are like a 'continued' story or arc?

Is 'The Nightmare' & 'Sisters of the Moon' connected?

What songs do you think can be related?

I hope this isn't a dumb question...

Just thought it would be cool to see what your opinions are!
