Here's a quick explanation from Dave in 1990:
"It's about this guy who happens to be named Dave, and he just has problems, and his friends all think he's crazy and he goes to see this fortune teller. She talks about how he feels, where he's going, how he gets there, and the fact that she knew he was coming and she's been waiting for him for a long time."
Sittin' up late at night
I tiptoe through the darkness
Cold as hell, black as spades
Aware of my immediate surrounding
