Illusion

I can't remember what the dream was about, but there was a song playing in the background with lyrics that were very suitable for the mood.

The song was "Illusion" by VNV Nation and the first two lines of the chorus are:
"Please don't go. I want you to say...
I don't want you to change for all the hurt you feel."

At the time I had this dream, I hardly knew this song, but there was no music playing while I was asleep. I suppose that somehow my subconscious has already memorized this song. When I woke up I turned on my computer, found that song, and played it immediately.
