I can't remember the beginning of the dream, other than to know that I was on a long journey (think Scrooge and his ghosts) with an old friend/coworker of mine from several companies ago. I liked this fellow a lot, admired his intelligence and perspective on the world, so I believe he was a guide in the dream.
I only remember the end, where we bumped into another coworker from the same company. He was spinning music, which is something he was into when I knew him, and we asked him to recommend some songs. We got to talking to him for a long time, until the dream ended, though I can't remember what we said.
