thought i heard music

Just a minute ago, sitting here in my living room, I was zoning out and really digging on this nice, hell of chill ambient music that was playing.  Then I realized there wasn't any music playing, and I'd started hearing high and low droning, like singing glass, amidst the wind in the trees and the crickets and the low wail of distant trains.

I'd say something like "man gotta lay off the drugs" but it's actually much nicer over here on this side.
