I had a dream recently. It was not “lucid dreaming”; it was a regular dream. In the dream I was clearing a table which had an uncorked bottle of wine, or maybe champagne. Accidentally I knocked the bottle over, and it started spilling its content emitting a swishing sound. At the same moment I started to wake up. When half awake and realizing it had just been a dream, I was still hearing the swishing sound; when fully awake, it stopped. Where was the sound? What made it?
And . . . what is the sound of one hand clapping?
