One feels we’re living a nightmare through the words presented here. They’re clearly designed to make one feel uneasy and terrified; certainly the worst to hear as far as a lullaby’s real purpose is concerned. Instead of relaxing you, it makes you feel bleak and hopeless, as this Prince of the underworld coaxes you to his hellish domain.
The use of repetition serves as a nice analogue to the downward spiral; that progresses further and further until you’re finally HIS plaything. I doubt one could sleep easy knowing they’ll soon be tortured for all eternity. All I gotta say is, you’ve done a good job with this emotional, free-verse piece. Please keep it up.
