My dream at first involved my placing certain objects in certain areas of some outdoor scene or venue, which was supposed to be done at more or less correct intervals (of time). But I was kind of getting ahead of myself and decided to wait a bit and start over. There was other stuff involved which is gone from my memory. As I began to wake up, the opening statement of Mahler's First played once, clear as a bell, in my head, and I realized those note intervals (the descending fourths over the sustained A) were exactly what the first part of the dream represented. Which I then immediately doubted, as dreams twist and turn, but even now it makes a weird kind of sense. I'm still trying to capture what the rest of the dream was, and I can't shake the feeling it related somehow to one the night before, or had the same tone.
