The obvious stuff: The narrator works night. It’s all dead end. His love life is also dead. He wants to find something/someone that will get things rolling again.
“Dancing in the dark.” is a metaphor for a pointless life of drudgery. (He wants some lovin’ and is not getting it. He says he is dancing in the dark, so that isn’t a reference to currently getting any.)
The question, what is this guy’s current job and what is the spark he is looking for?
“I’m sick of sitting 'round here trying to write this book.”
He is trying to write a book. Really? Why the night work part? Is that to bring in income? Or is it a metaphor? As in the above mentioned self-reference: the book is a hit song and his night work is generic club gigs.
“I need a love reaction, come on baby give me just one look.” That’s the spark he needs. He either needs a muse or his current girlfriend isn’t giving any inspiration.
So I’d say that it’s about a down and out musician/songwriter is a pretty good guess.
(And of course it involves sex. All rock 'n roll songs are about sex.)
