I joined in playing with a group of people in a very interesting version of Bulgarian (or similar) folk song. I played on an improvised flute made of white electrical tubing (!). It was very beautiful in an unusual way, and I experienced a deep satisfaction in it.
I used to play music (keyboard and electronic) but haven’t done so for several years. Recently, I have wanted to come back into it again. It fills something in me that nothings else does. My sense is that the dream can be taken in a quite literal way, maybe with exception of the particular instrument! It gave the dream the quality of improvisation, of suddenly and unexpectedly becoming engaged, and something very beautiful coming out of it.
