I believe this song is talking about a person who is either on the verge of death or is close to someone who is dying and wants things to change for the better. They might think that if they leave the life they are currently living, it would be better for not only them (because they get to go to heaven) but it would also be better for the people close to them because then wont have to see then in pain and agony anymore. Its also about letting go of something you have no hope in. (in the music video) The (whats believed to be) Angel of Death comes to take the select few prople to heaven surrounded by a glowing miraculous light. This is a very accurate interpretation of what could happen in near-death and time-of-death experiences, as told by people who have had these experiences. It was as if they were walking closer to a white light beckoning for them.
I think it could be about the people who are suffered and damaged. The angel is coming down to take them to the world where their pain is not brought to the light "leave me forever in the dark". There's many pieces of their artwork in the vid. At the end, the guy's already gone(dead), but the angel finally takes him to heaven
I'm pretty sure it's about someone loosing their way in life, someone who's fading and loosing touch with the people in their life...and no matter how much they don't want it to change they have nothing to do but accept it, and move on. However this song could mean many things, this is just one of the theories.
To give a sign if you like them
I think it is about someone who is feeling lost and trying to reach out to someone else who isn't really much better than them.
