I'll dream music from time to time. Dream music is amazing, probably because there're no filters when we're in the land of nod - it's some sort of idealistic purity.
In one dream I was in a basement, friends were all around partying, having fun, causing chaos... Alfred Brendel comes walking down and plays some stunning Liszt on the walls (there's never a piano around when ya need one!), everyone's amazed. I've never thought to play piano on a wall so I gave it a shot, and to my surprise I did very well, until I started thinking about it and it all fell apart. Brendel tells me to keep practicing, then goes upstairs with everyone else to party in the kitchen.
I stayed downstairs practicing on the wall until dinosaurs came rampaging through a time portal. Sid was upset that dinosaurs were making a mess of her house so I went after 'em with grenades. Brendel must have left, can't be fighting dinosaurs at his age.
