Thank you for your analysis, MaryAnn; you've saved me a lot of time in putting together my own thoughts, as I concur with yours. I also appreciate Richard's statement, Who hasn't at one time woke up in the middle of the night haunted by his past?

The only discordant note in the poem, for me, is the "human voice full of pain and anger," which doesn't seem to be reconciled with the fire siren at the end of the poem. I realize that the Sirens weren't human either, but, if I remember correctly, they appeared to be women. Help?
