What a weird dream.

I dreamt I was cooking dinner, suddenly realized I was out of sunscreen (I didn't need it for the dinner. It was just a completely unrelated thought) and needed to go get some. I briefly contemplated waiting until after I ate. Then, realizing I was also out of silverware, I left right away.
But then my dream flitted to me eating dinner, and then again to cooking dinner at the point where I needed sunscreen and then again deciding to go get some...and the dream sort of looped a couple of times before I set out.
It was late at night. I couldn't decide whether to walk to Walgreens or to some now-vague other store which was a lot farther away, but which made sense at the time.
I set out in a random direction, planting each footfall carefully as I walked, so as to avoid stumbling, because it was pitch dark. My hands were outstretched to avoid bumping into anything.
Then I tried running. Running in the dark was thrilling. Then I said to myself, hey, this is stupid. Running in the dark is a great way to get hurt. Then I ran some more (a therapist would have a field day with this dream).
I quickly got lost. There were small scrubby trees and bushes, lots of rocks and boulders. There was very little grass, but lots of thick sandy dirt. I felt like I should know where I was. I kept telling myself that if only it were light enough I would surely spot a landmark I recognized.
I found it quite amusing. I was exasperated and angry that I couldn't get my bearings, but at the same time I thought it was pretty funny.
And-as in many of my dreams- I kept looping back to previous segments, or jumping forward again to some other portion, as if I were using the 'scene select' option on my dream DVD player. Thus I'd be proceeding slowly, groping my way, then I'd be back in the kitchen, then running in the dark, in the kitchen again, then running again, and so on.
Every so often I would pass under a street light which illuminated my surroundings enough that I could almost make out something I almost recognized in the distance, but I had to leave the light to see it more clearly and then I was lost again. I have no idea where the street lights came from, because I wasn't on a street. But the lights were there and made perfect sense.
The landmarks I almost recognized were pretty weird, too. At one point I thought I saw the now-defunct Arby's which was at Shelbyville Rd/Hubbards Ln. I remember walking towards it and thinking I'd run into either it or the (also closed) ice cream place across the street.
I don't remember what else I thought I recognized, but it seems they were mostly local. At the same time, though, there were no actual streets, just dirt and boulders and shrubs, and I remember being careful to avoid any cacti, though I never saw or felt a single cactus. It was like I was lost on the Llano Estacado but it was in Louisville.
Then I woke up.
When I woke I realized that the dream also had a soundtrack of a single song, and I'd really liked the song a lot, but I couldn't quite place what the song was.
I racked my brain trying to figure it out, but the details were very sketchy. Female singer- maybe Rosanne Cash? The longer I thought about it the sketchier it became, until I lost the tune, the voice, the beat, everything. Now I'm not even sure it was a song I'd ever heard before, or if I even heard it in the dream.
Strange.

I don't know anything about dream interpretation. If I had to take a stab I'd say it means 1) I feel lost, and 2)I've read too much Cormac McCarthy lately and need to read something that's not set in the Texas/New Mexico/Mexico desert.
But I don't feel particularly lost, and I've just about run through all McCarthy's novels already anyway, so I'm not sure how helpful the dream was.
