Wake the dead
Serial sleepers slay with words unsaid
Sleep with the light on
Keep the lonliness away
I feel the darkness anyway
And I reach for the doorknob
Wake the dead
Serial sleepers slay with words unsaid
Oooh [ Lyrics from: http://www.lyricsmode.com/lyrics/h/house_of_heroes/serial_sleepers.html ]
Rise up oh sons of God
And sing the song that hides behind your teeth
These ears have longed to hear
All night long
Waiting for love
Save our souls before all our dreams come true!
Wake the dead
Serial sleeps slay with words unsaid
I also think that it means that if someone is doing something that is harming themselves or somebody else, either mentally or phisically, and you don't do anything to help them you are more or less "killing" them more. Many people don't help people who need it. They try to even avoid noticing than trying to make a change. There are many people out there who need to hear the gospel.
I think that this song means that christians go through life with their eyes closed and sit back while people go through their whole life without hearing the gospel.
