An almost last min completion of the bonus task!

My awareness goes up and I recall the bonus task: create a new song on an instrument that doesn't exist in waking life. I have some doubts about how exactly am about to proceed as I haven't really considered this during the day. At this moment two butterflies appear in front of me and I briefly fix them one next to each other thinking this will make for a perfect instrument. Now the only thing that's left is for me to start playing. After moving the glued double butterfly instrument around a bit (I think at this point it started making the drumming sound), I take the two butterflies apart and holding one in each hand, I start producing the song by methodically tapping with them the corners of an invisible frame. This results in perfect drumming sounds. I repeat this movement until the beat and melody is solidified in my mind and then allow for further beat variation. Happy to have completed the task I briefly think about the experience. The dream/scene soon dissolves.
