Ok I have been told time over that I have a wraith following me, but have been told different things about what they really are. I have been told they are completely harmless and others have said they're agressive and will attempt to suck out my life force, others say they represent my up coming death. I just want to find out what exactly they are and if I should be worried. If they are dangerous then how do I get rid of one. Even though I have been told tons of times it's a wraith could I still be mistaken. I would would be so thankful for any help I can get on this.
