Do you have OCD? (Obsessive Compulsive Disorder)
That keeps you dwelling a lot.
I'll have a song I love and then it gets stcuk in my head. I try and change it to another song and sometimes it works.
During the time we were in hiding from Hurricane Frances, I had a Blue Oyster Cult song stuck in my head. I love the song, but I wanted it OUT!
I get thoughts that race through my head. They could be good thoughts at first, but sometimes they turn to bad thoughts. When they start to multiply, that is the time to do something. Get up, go for a walk, excercise, take a cold shower. Go talk to someone you know. Do anything to break the cycle.
Worst time it happens is at work.
