I think this song is about giving up and hiding from your problems rather than facing them, and how that never solves anything. Possibly suicide, as you could see here:
"Better it would be to sleep forever
In silent shades of the evernight
Sweet are the dreams in the groves of death"
Death could be, and often is, thought of as sleeping forever, and the grove of death is pretty self-explanatory.
