A dream about scales

I recently started taking guitar lessons (again). That means I'm practicing every day now, including thirty minutes of playing scales daily.

Last night I had a strange dream about playing scales. The key of F had recently passed away. Apparently, musical keys were like people who were among us and then departed. I was setting up for a DCIC show just after F's passing and we wanted to play something as a memorial. The dream quickly turned into an anxiety dream where I was desperately trying to decide what scales I could play that would somehow evoke F, even though F was gone so I couldn't play anything in F. I never did come up with a good solution.
