I definitely think it has something to do with paranoia, like he can feel something bad is about to happen to him. It keeps him looking over his shoulder. But it may also be an insubstantial fear based on superstition and imagined dangers. And I heartily agree with Karatepop, Donovan's voice is love. Anybody who hasn't, needs to listen to "Universal Soldier."
