I must be very bored if I go into a thread with a generic title.
That said, I tend to start singing, without noticing, some song that I haven't heard in a very long time, and when I realize it, I also realize that the lyrics are relevant to my thoughts / situation at the moment. It's an unconscious association process, I guess.
