Cover art for Vet For the Insane lyrics by Fields Of The Nephilim

It reads to me as a third person narrative of someone who's been committed for murdering their loved one. It's a horror story with a twist.

@feufollet - I agree - sounds like a jealous lover committed to an asylum because he keeps saying he wants to go home so he must have done something real bad to her and is probably disconnected as to what crime he has committed. He may have been there before so as the subtitle - Mr. Jealousy has returned.
