Lyric discussion by ScaredOfHimself 

Cover art for Deliverance lyrics by Opeth

It could be taken as thoughts that repeat themselves compulsively in your head over and over. ones that you know are seperate from reality but are illusions that you dont know how to defuse. they could be suffocating through someone else and cope through hatered. they then seek revenge blindly to feed their own self destruction as their means of coping.
