In last night's dream, little of which I can remember at all, I was with a large group of people getting instructions from SNL cast member Jimmy Fallon on the art of improvisation. We were all standing in a line in this narrow hall and he had each of us make up some sort of short improv about what we ate for dinner last night. When it was my turn, I took a step out of the line and said, "A roll", and just as I was about to step back into my place he motioned for me to continue. I went on about jelly, and toasting the roll, and ended up singing that obnoxious Limp Bizkit song, "Rollin' ". Jimmy ended up just giving me a look of disapproval and I returned to my place in the line.
I don't remember much else other than this image in my mind of standing on a dock and looking along the shoreline of a lake out onto a boat.
