I believe he is talking about him looking at lots of choices for a life he wants. I also think he is trying to see why his life All these oportunities and wants one that sets him for a good life. I picture him looking at a broken mirrior at himself and thinking what he can do to change his life and how he can fix his mistakes searching for an answer. I can also see him using the filament as a nother term for an idea to spark his new life in a positive way. I like this line hopefully i can hear this song later and find the meaning to it. I think these lyrics may be about a lost hope he is picturing for himself and it may possibly be about a loved one or an addiction i just can't seem to put it together until i hear the whole song.
