I had this dream camping in Pennsylvania a few days ago. I was transported back in time to age 18, then as an 18 year-old, transported back to post WWII France. It seemed my uncle H needed some kind of mechanical part and my mother dispatched me from Toronto to France to deliver it to him. Off I went. It turns out that part was for a home-made musical instrument, but I don't recall the specifics. I recall that H was playing a clarinet-like horn whose bell looked like somebody's good silver-wear, very elaborate. H had an orchestra of noise musicians in my dream who all played wacky instruments. I was invited to join the band. I happened to have my button accordion there, even though at 18 I didn't play the button accordion. Some guy offered to convert it to a horn by adding a mouthpiece and a hose. I accepted the offer. H lived in an elaborate apartment with off-white broadloom and everyone was tracking mud through the apartment. H just kept saying, oh don't worry yourself over that.
Finally it was time to go home and I was taken to the airport. This led to a second part of the dream which I don't recall except that it had to do with an adventure lost in a parking garage at the airport in Paris.
