Death's Diary

I am a doctor of death, Curing my patients of breath Their cries are my lullaby; One look at me is enough to horrify My mind is a deadly disease; I can take your soul away with a simple brease They all cry out 'please stop you're scaring me' But I'm not sure that they can really see, That I can't control this awful energy; Each word they say leaves a haunting memory Looking at my world as a whole, It's hard to tell who's really in control
